The COM-100 is a professional grade level EC/TDS/Temp meter ideal for all water quality testing applications such as hydroponics, water purification applications, wastewater regulation, aquaculture, colloidal silver, labs & scientific testing, pools & spas, ecology testing, boilers & cooling towers, water treatment and more.

• Measures electrical conductivity (EC), total dissolved solids (TDS), salinity and temperature.

• 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.
