Rugged, water resistant (IP 67) designed for field use PC interface (USB / serial or analog) Data logger and alarm function (min./max.) Good Laboratory Practice (GLP-features) Clear, concise result reading: easy-to-read backlit LCD display Automatic temperature compensation Dirt-insensitive up-to-date 4-pole conductivity cell offering highest precision (SD 320 Con)
Min / Max Value Memory highest and lowest measured value is saved Auto Hold freeze and display measurement Auto Power Off if unused, the meter automatically switches off after a selected period (0 to 120 min, or deactivated) Low Battery Display €œBAT€ Automatic temperature compensation As conductivity depends strongly on temperature, each conductivity value is only valid at the corresponding temperature. Therefore the device supports temperature compensation, i.e. referring the conductivity to a reference temperature (selectable: 20 °C or 25 °C). Salinity measurement Salinity means the sum of amount of all dissolved salts in water. The unit is g / kg. TDS measurement (total dissolved solids) TDS means the mass concentration of dissolved media in a liquid. The unit is mg/l.
