EXTECH RE300 ORP Waterproof Meter

The Extech RE300 ExStik® ORP Waterproof Meter is a portable, rugged device designed for immediate and accurate oxidation-reduction potential (ORP) measurements. It features flat surface electrodes for on-the-spot testing, with a measurement range from -999 to 999 mV and an accuracy of ±4 mV. The meter includes automatic electronic self-calibration, a simulated analog bar graph to display changes, and a large 3.5-digit digital display with a bar graph. It offers memory storage for 15 readings, data validation indicators, data hold function, auto shut-off, and low battery indication. The interchangeable electrode module can be used with pH and chlorine measurement modules, which are automatically recognized by a built-in chip. Waterproof to IP57 standards, it floats in water and is protected in wet environments. The kit includes the meter, electrode, protective sensor cap, sample cup, four CR-2032 batteries, and a neck strap. An optional weighted base is available to hold the meter and sample cup.
