HM Digital Waterproof Professional Series pH/EC/TDS/Temp Meter

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

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

Automatic Temperature Compensation (ATC) using three temperature coefficients

Waterproof housing (IP-67 rating)

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

Auto-off function, data-hold function and low-battery indicator

Display: large and easy-to-read LCD screen includes simultaneous temperature reading

Replaceable Sensor (model SP-C3)

Factory Calibrated (pH/EC/TDS)

Includes translucent cap, 2 (AAA) alkaline batteries, pH 4 & 7 calibration solutions, pH storage solution and lanyard
