1978 — Hanna Opens in Italy
Hanna was founded in Padua, Italy.
1980 — World’s first single-probe portable conductivity meter
The HI8033 is a four pole conductivity meter designed for soil testing in agriculture. The potentiometric probe allows measurements of different solutions with different conductivity values. The same meter can be used to measure both deionized water and fertilizer solution.
1982 — World’s first pH controlled chemical dosing pump
The DP7916 combined a pH meter with a chemical dosing pump in order to maintain a desired set point of a process applications. The BL7916 is the second-generation design and is still widely used by many customers including plating, wastewater treatment, water treatment and swimming pools.
1984 — World’s first microprocessor-based hand held pH meter
The HI8424 was the first portable microprocessor pH meter. The microprocessor allowed for automatic calibration as compared to manual calibration with trimmers or potentiometers. The calibration information was stored in the meter even when it was powered off.
1985 — World’s first pH electrode with built-in temperature sensor
The HI8414 pH meter was the first meter to use a pH electrode (HI1213S) with a built in temperature sensor. The temperature sensor allowed for the automatic correction for changes in pH with changes in temperature as calculated by the Nernst equation. This advancement is now commonplace in the industry.
1986 — World’s first electronic pocket sized pH tester
The pHep® or pH electronic paper revolutionized the way pH can be measured. This tester brought the electronic pH measurement to the masses. It allowed farmers, students, and many other users access to a pH meter that was simple to use and very accurate.
1988 — World’s first pre-amplified pH electrode
Amphel was the first pH electrodes with a built in amplifier. The pH electrode produces a high impedance signal. Due to the low current signal the measurement is susceptible to electrical noise, humidity, and a bad connection. Utilizing an amplifier allowed for signal with a higher current, which overcame the measurement issues. We continue to use amplifiers in many electrodes including some of those with built in temperature sensors.
1990 — World’s first waterproof portable pH meter
The HI9023 was the first waterproof portable pH meter. A pH measurement is usual for many industrial and environmental applications. In these situations it is common that a pH meter can get wet. If water or chemical solutions get inside the meter then it is possible that the sensitive electronics can be damaged. For this reason Hanna Instruments designed a meter that would be completely waterproof. The HI9023 and successive portables including the HI9024, HI9025 and HI9026 have been the work horse meter for many customers that need a rugged waterproof meter.
1991 — World’s first replaceable electrode pH pocket tester
The Checker® 1 (HI98103) was the first pocket pH meter that had a replaceable electrode. The HI1270 pH electrode has a screw cap threaded end that was simple to replace extending the list of the pH meter. The Checker is by far the most popular and recognizable tester in the market with over 1 million meters used. The Checker is still in production and continues to be one of the most popular meters.
1992 — World’s first portable pH meter with plain-paper printer
The HI9224 was the first portable pH meter with a built in printer. The addition of the printer to a meter was for the customers that required unalterable documentation. This is a great value for many industries including in the pharmaceutical and food industries.
1995 — World’s first pocket thermometer with CAL Check™
The Checktemp® series of pocket thermometers were the first thermometers that incorporated a unique calibration check feature for determining any drift of the internal electronics. A switch is used to place the thermometer in CAL Check mode. If the reading was inside ±0.3°C from 0.0°C reference point that is simulated then the internal electronics are within an acceptable tolerance.
1997 — World’s first pH tester with double junction electrode
The pHel pH testers were the first pocket size meters with a double junction. Many industries have metals or other compounds that react and form a precipitate with silver ions from the silver chloride found in a single junction reference design. With a double junction electrode the silver chloride is located in an inner compartment while an outer compartment is silver free. This design extended the life of an electrode and was useful for customers that preferred the convenience of a tester with features of a traditional laboratory electrode.
1999 — World’s first pH/temperature tester with dual-level LCD
The pHep®4 and 5 were the second generation of the original pHep. These meters used a large dual-level LCD that allowed many advance features that would only be found on more expensive portable and benchtop instrumentation. The Dual level LCD was able to display both pH and Temperature simultaneously along with a battery and stability indicators. The meters also feature automatic temperature compensation, automatic calibration, battery percent level at start up, waterproof, and a replaceable electrode. pHep 4 and 5 set the standard for all instrumentation manufacturers that offer handheld testers.
2000 — World’s first multiparameter (pH/conductivity/temperature) pocket tester
The Combo pH/EC/TDS/Temperature meters were the first testers to combine pH and conductivity sensors into a single meter. They offered all the features of the redesigned pHep handheld testers with the addition of a graphite amperometric sensor for the measurement of EC and TDS. The Combo meters also had a exposed temperature sensor that allowed for a quick and accurate temperature compensation for both pH and conductivity measurements.
2002 — World’s first colorimeter with CAL Check™ feature
The HI95 series of portable photometers were the second generation of our single parameter photometers. The HI93 series first generation meters used an LED at a specific wavelength as a light source. The HI95 series optical system was improved to use a tungsten lamp and narrow band interference filter for a much narrower spectral bandwidth. Hanna Instruments also incorporated a unique CAL Check function in which a traceable secondary standard is used to check the pre-programmed curve. If readings are outside a specified tolerance then the unit could be calibrated with the standards and an offset to the curve applied.
2003 — World’s first pH meter with
Many problems in pH measurement result from a lack of understanding of the Nernstian response for a pH electrode. Every pH electrode generates a mV response in solutions at a specific pH. By monitoring the offset and slope characteristics of a pH electrode during the calibration process it is possible to determine potential problems The pH221 and pH222 were the first pH meters to offer a unique CAL Check feature. During calibration these meters would alert the user if the probe needs to be cleaned or the buffer is contaminated. After calibration the probe condition (based on offset and slope) and the probe response were displayed with a five bar indicator. The greater the number of bars the better the condition and response.
2004 — World’s first process pH meter with integrated cellular communication
The ability for remote data acquisition is becoming of increasing importance. Many times it is convenient to monitor a process parameter remotely. With the HI504900 GSM module it is possible to use a SIM card from cellular provider to transmit measurement data over a cellular connection. The HI504 process pH/mV controller allows for the digital transmission of data by using an RS485 serial connection. The HI504 allows for programming responses based on measurement criteria. These responses include the use of sending a text (SMS) messages over the cellular connection.
2004 — World’s first pH/ORP combo tester
The measurement of pH and ORP is very common for industries that rely upon oxidizers for sanitization or to promote an oxidation reaction such as with the oxidation of cyanide to cyanate for the treatment of plating wastewater. Both pH and ORP measurements are also made for chemical reactions that use a reducing agent. The ORP generated by oxidizers and reductants are dependent on the pH of the solution. Many times there is enough oxidizer or reductant present but the pH is not at the optimum. With the HI98121 it is possible to monitor both pH and ORP at the same time. The HI98121 is commonly used to monitor pH and chlorine for many applications including swimming, food sanitization, plating wastewater treatment, and cooling tower water treatment.
2005 — World’s first single parameter line of auto titrators for wine testing
Total titratable acidity and sulfur dioxide are two important parameters that are measured during the wine making process. To measure these parameters either a pH/mV meter would be used with a volumetric burette or a very expensive and complex titration system is used. Hanna Instruments developed the HI84100 (sulfur dioxide) and HI84102 (acidity) titrators for the wine industry. Both meters were inexpensive and simple to operate. All the chemistry used is premixed and the end point criteria pre-programmed. These meters allowed for the winemaker to perform analytical measurements without the need for sending samples to a lab.
2010 — World’s first handheld colorimeters (Checker®HC) to offer ease of use and high accuracy in a palm sized design
The Checker HC handheld colorimeter series are the first single parameter colorimeters available in a convenient palm size design. Before the Checker HC colorimeters the user either used a expensive $200-300 portable photometer or they used an inexpensive chemical test kit. The chemical test kits offer the advantage of being inexpensive but they do not provide the high degree of resolution or the non-subjective nature of a photometer. The Checker HC’s provide the benefits of a colorimeter at a price point of a chemical test kit. The Checker HC’s, like the pHep, are another prime example of Hanna Instruments bringing technology to people that would not normally think of using.
2013 — World’s most innovative pH, EC and DO handheld/portable/wall-mount meter...edge®
edge is the thinnest multiparameter meter available. At just 0.5” thick the edge is loaded with many of the features found in expensive benchtop instrumentation. Features include data logging, USB ports, CAL Check™, auto ranging EC /TDS ranges, and GLP data review. edge uses digital pH, ORP, EC and DO probes with a small 3.5 mm connector. The edge is extremely versatile in that it can be used as a portable, benchtop or even as a wall mount indicator.
2014 — “World’s first pH electrode with Bluetooth Smart technology (HALO®)
The HI11312 HALO is the world’s first professional pH probe with Bluetooth Smart technology (Bluetooth 4.0). It is a high quality, double junction, refillable glass pH probe with a built-in temperature sensor that can be used virtually anywhere: in the field, laboratory or classroom. HALO transmits measurement data wirelessly to a compatible smart phone or tablet running the Hanna Lab App. Since the introduction of HALO in 2014 the family has grown to include other specialized electrodes including the FC2022 pH electrode for the measurement of pH in food products. Halo has set the new standard in technology for pH measurement that will be commonplace in the future.
2015 — World’s first pH electrode and meter with Bluetooth Smart technology (HALO and edge blu)
The edge blu is the first Bluetooth enabled pH meter for the use with HALO Bluetooth pH electrodes. The edge blu receives measurement data wirelessly from the Halo pH electrode. The logging of data by the meter is performed by touching the HALO pH electrode button. The type of logging mode used is based on the setup configuration of edge blu. Data is logged at interval, on demand or by stability.
2016 — World’s first colorimeter with tutorial mode
The HI97 series of portable meters are the first photometers to have a tutorial mode that guides a novice user in performing the analytical measurement. These meters display step-by-step instructions and animations that allow anyone to perform a measurement without having to read from an instruction manual.
2017 — World’s first pH and pump controller with smart electrode
The BL120 and BL121 swimming pool controllers with built-in dosing pumps for the automatic dosing of an acid and chlorine to a swimming pool are the first for a combined dosing system to utilize a digital probe. The digital probe measures pH, ORP, and temperature and transfers the measurement information digitally to the swimming pool controller. The digital technology is less prone to electrical interferences from pumps and humidity due to the measurement being in the probe and then transmitted digitally as compared to analog probes.
2019 — First complete line of pH testers with application specific probes for the food and beverage industries.
One of the most critical aspects of pH measurements is using a pH sensor that has the correct glass, tip shape and reference junction for the intended purpose. In 2019 Hanna introduced 10 application specific pH testers that are designed for a particular use. These testers include ones for the measurement of soil, beer, wine, meat, and cheese to name just a few. Having the correct probe design will provide for a better measurement and a longer life of the sensor.
2020 — World’s first pH and pump controller with cloud connectivity and smart electrode
The BL121 and BL122 swimming pool controllers with built-in dosing pumps are the first controllers of their kind that offer cloud connectivity for remote monitoring. The cloud connectivity allows for service companies and pool owners to monitor the pH/ORP levels of a swimming pool and be notified when there are errors including alarm relay activation.
2021 — World's first multiparameter meter with optical dissolved oxygen technology to have Bluetooth® connectivity
The HI98494 is the first multiparameter meter with optical dissolved oxygen technology and Bluetooth® connectivity for transferring data to a smart device and the Hanna Lab App. The Hanna Lab App is both Apple® and Android® compatible and allows for review of data in tabulated or graphic form. Data can be shared via e-mail, message, or AirDrop from the Hanna Lab app as a .csv or .pdf file.
