    Extech RE300 ExStik Waterproof ORP Meter

    The Extech RE300 ORP Meter measures ORP/Redox from -999 to 999mV. It has an automatic, electronic self-calibration and a simulated analog bargraph that displays fast changes in ORP readings.

    ORP stands for oxidation-reduction potential, which is a measure, in millivolts, of the tendency of a chemical substance to oxidize or reduce another chemical substance.

    Applications that use ORP for monitoring and controlling oxidation-reduction reactions include cyanide destruction, dechlorination, chromate reduction, hypochlorite bleach production, and chlorine and chlorine dioxide scrubber monitoring using bisulfite.
    ORP is measured in some instances for the control of biological growth. The principle behind these applications is that a minimum ORP value will successfully destroy microorganisms. This approach has been used in the chlorination of swimming pools and cooling towers. It should be noted that both of these applications also include pH control.

    Additional Features

    The RE300 ORP Meter has a high resolution of 1mV and a memory that stores and recalls up to 15 readings and it saves the last calibrated value. The data validation indicators show the user that the reading is stabilized and it features data hold, auto shut-off, and low battery indication. This meter has a IP57 waterproof rating.

    Applications:

    • Water treatment
    • Wastewater
    • Groundwater
    • Aquaculture
    • Fisheries management
