Measures Potential Hydrogen (pH), Electrical Conductivity (EC), Total Dissolved Solids (TDS), Salinity and Temperature

Four scales: pH, mS, ppm 0.5 (NaCl) Scale & 0.7 (442™) Scale

Automatic Temperature Compensation (ATC) using three temperature coefficients

Digital Calibration (push button) to any point within the meter’s range

Data-hold function (Max. 6 data values)

Large and easy-to-read LCD Screen

Displays 3 parameters (pH/EC or TDS/Temp) simultaneously.

Replaceable Sensors (model SP-C2 for Conductivity, SP-P5 for pH)

Factory Calibrated (pH/EC/TDS)

Includes power cable, pH 4 & 7 calibration solutions, pH storage solution
