The Extech RE300 ExStik ORP Meter with Flat Surface ORP Electrode provides accurate and high-resolution ORP/Redox measurements from -999 to 999mV, with a resolution of 1mV and 4mV accuracy. Designed for professionals in water quality and environmental testing, the RE300 features a flat surface electrode for optimal contact and performance.
Convenient features include automatic electronic self calibration, data validation indicators, Data Hold, and Auto Power Off to conserve battery life. A simulated analog bargraph dynamically shows ORP changes, while the built-in memory stores and recalls up to 15 readings and retains the last calibration value.
