4Swimming Pool Water

5surface water

3、 Performance characteristics

1、 Memory limit/Lower limit value: can store upper limit values andlower limitprice

2、 Auto hold: Freeze and display measurement results

3、 Automatic shutdown: If not in use, the instrument will automatically shut down at the set time（0to120Minutes, automatic shutdown)

4、 Low battery display:“BAT”

5、 Automatic temperature compensation: Temperature has a strong interference on conductivity, and each conductivity value corresponds to different temperatures.SD320Support automatic temperature compensation, which refers to the conductivity and reference temperature (optional:20℃perhaps25℃）.

6、 Salinity measurement: Salinity refers to the total amount of salt dissolved in water, measured in units ofg/kg.

7、 TDSMeasurement (total dissolved solids):TDSIt refers to the mass concentration of the liquid that dissolves the medium, measured in milligrams/Raise.
