ORP testers are available with or without a replaceable probe. A ORP tester with a pH probe is also available.
Portable meters are available as:
- Meters with BNC connectors and a mV scale.
- Multiparameter meters from ones with both pH/ORP sensors in a single probe to probes that have pH/ORP, EC, DO, and turbidity sensors.
Benchtop meters are available with a BNC connector that accept either a combination ORP probe or half cells. Multiparameter benchtop meters are available that can also measure other key water quality parameters including conductivity and specific ions such as fluoride, nitrate, and many others.
Electrodes & Probes
The following are replacement probes for benchtops, portables and testers.
Hanna ORP solutions include ORP test solutions for verifying sensor performance along with storage and pretreatment solutions. Pretreatment solutions include both reducing and oxidizing pretreatment to condition the probe and increase response time. Hanna solutions have the lot number and expiration date clearly marked on the label and is air tight with a tamper-proof seal to ensure the quality of the solution. Other solutions include storage and probe refill solutions.
Accessories include shockproof rubber boots used with portable meters to offer additional protection against accidental drops of the meter. The shockproof rubber boots offer increase the tactile feel of the meter giving it a non-slip like grip. Other accessories included replacement items supplied with some of the multiparameter meters.
Process controllers are available for the continuous monitoring of solutions. These meters can be used to monitor and display results in real time while controllers offer the ability to use a relay to activate a solenoid valve, dosing pump, or other device to make adjustments to a process. This is useful for many applications including maintaining the oxidizing level of swimming pools, food rinse baths, and cooling tower maintenance. Some controllers offer analog and digital outputs for connection to a remote device such as SCADA, PLC or other compatible devices.
Process ORP probes are available for both in-line and submersion mounting.
