ExStik® Conductivity/ TDS/Salinity Meter (Extech EC400)

Waterproof, high accuracy, multi-range sensor, measures four parameters: conductivity, Total Dissolved Solids (TDS), salinity and temperature.
Autoranging meter offers 3 ranges to measure from pure water to salinity solution to waste, boiler and cooling water using the same conductivity cell. 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 powering up.
Includes four CR2032 lithium ion batteries; replacement 3039-51.
