    EC400 Exstik Conductivity Meter

    The Extech EC400 is a 4-in-1 multi-range sensor for measuring Conductivity, TDS, Salinity and Temperature

    The Extech EC400 ExStik® features six units of measure, internal memory that stores up to 15 labeled readings for easy recall, adjustable conductivity to TDS ratio factor from 0.4 to 1.0, and self-calibration upon power up.

    • Autoranging meter offers 3 ranges to measure from pure water to salinity solution to waste, boiler and cooling water using the same conductivity cel

    • 6 selectable units of measure: μS, mS, ppm, ppt, mg/L, and g/L

    • Internal memory stores up to 15 labeled readings for easy recall

    • Adjustable Conductivity to TDS ratio factor from 0.4 to 1.0

    • Self calibration on power up

    ExStik II Conductivity/TDS/Salinity/Temperature Kit

    The Extech EC400 ExStik features six units of measure (µS/cm, mS/cm, ppm, ppt, mg/L, and g/L), internal memory that stores up to 15 labeled readings for easy recall, adjustable conductivity to TDS ratio factor from 0.4 to 1.0, 0.5 fixed salinity ratio, and self-calibration upon power up.

    Additional Features

    Incorporating the latest microprocessor chip and patented sensor technologies to enable the simultaneous measurement of Conductivity, TDS, Salinity, and Temperature, the EC400 provides the flexibility of interchangeable cell constants and has made the job of testing fast, accurate, and repeatable. The EC400 is also waterproof to IP57 for use in wet environments and floats if dropped in liquid.
