For conductivity this PH/ISE and Conductivity Bench Meter features EC, resistivity, TDS and salinity measuring scales and stages 1, 2 and 3 USP modes plus linear and natural water temperature compensation. EC has an extended range from 0.001 µS/cm to 1 S/cm with auto recognition of the probe type used. Salinity measurements can be displayed in practical salinity, natural sea water or in percent scale.
Special Features :
Direct calibration with measurements in multiple units.
Incremental methods include:
The Hanna HI 4522 is supplied with 4-ring EC probe
Glass body pH electrode
pH 4 and pH 7 buffer solutions
Electrode refilling solution
