The COM-360 is a professional grade level pH/EC/TDS/Temp meter ideal for all water quality testing, hydroponics, water purification applications, wastewater regulation, aquaculture, colloidal silver, labs & scientific testing, pools & spas, ecology testing, boilers & cooling towers, water treatment and more.

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

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

• Automatic Temperature Compensation (ATC) using three temperature coefficients

• Water-resistant housing

• 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-CP)
