ORP / Temp Meter

The ORP-200 - Waterproof 

Oxygen Reduction Potential and
Temperature Meter

Oxygen Reduction Potential and Temperature Meter

Ideal for all ORP testing, including anti-oxidant measurement, water purification applications, chlorine monitoring, environmental testing, fruit & vegetable washing, pools & spas and water treatment.

What is ORP?

Oxidation Reduction Potential (ORP) is a measurement of the oxidation effectiveness of a sanitizer such as chlorine or bromine. OPR is typically meaured in milli-volts and can be an effective tool to use in drinking water.


• Measures Oxidation Reduction Potential (Redox) and Temperature.

• Auto-ranging calibration with digital fine tuning.

• Includes 4 pH buffer solution in a sponge embedded in a clear cap.

• Waterproof housing (IP-67 rating).

• Simultaneous temperature display.

• Digital Calibration (push button).

• Auto-off function, data-hold function and low-battery indicator.

• Display: large and easy-to-read LCD screen includes simultaneous temperature reading.

• Factory Calibrated: The ORP-200 meter is factory calibrated to +200 mV. The meter can be easily recalibrated with digital calibration using the push buttons, rather than a screwdriver.

• Includes a cap, batteries, and lanyard.
