The Extech Waterproof ExStik Conductivity/TDS/Salinity Meter EC400 is a high accuracy multi-range sensor that can measure four parameters (conductivity, TDS, salinity, and temperature). The EC400 autoranging meter offers 3 different ranges to measure from pure water to waste water and any solution that requires a conductivity and salinity measurement using the same conductivity cell. The EC400 has 6 user selected units of measure: µS/cm, mS/cm, ppm, ppt, mg/L, and g/L. For easy recall, the internal memory can store up to 15 labeled readings. The conductivity to TDS ratio factor can be adjusted from 0.4 to 1.0. The Extech EC400 has the convenient function of self calibrating on start up. The conductivity cell module is easy to replace and the waterproof design is able to withstand a wet environment. The EC400 can simultaneously display conductivity or TDS plus temperature.
