The HM Digital ORP-200 ORP Meter Water Tester with Temperature Gauge is a water tester used to test the Oxidation Reduction Potential (ORP) in your water supply. It also tests the temperature of water, and features Automatic Temperature Compensation (ATC).

Useful for both consumers and hobbyists, it can be used to test your drinking water, pools, spas, jacuzzis, aquariums, hydroponic systems, various water purification applications, water for alcohol brewing, ionizers, agriculture, environmental testing, fruit and vegetable washing, metal finishing, ozone system monitoring, pharmaceutical and medical applications, and other applications where you need to test the ORP and/or temperature of water. The HM Digital OPR-200 water tester is useful for all ORP testing, including anti-oxidant measurement.

The HM Digital ORP-200 has a multitude of advanced water quality testing features. It measures potentially harmful oxidation reduction potential in the range of -999 to +1000 mV.
