Features 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 “BAT”

 

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.
