The only handheld/portable TDS meter / EC meter with full scale digital calibration.
A water tester that is perfect for both consumer or commercial use.
Ideal for all water quality testing, water purification applications, wastewater regulation, aquaculture, hydroponics, colloidal silver, labs & scientific testing, pools & spas, ecology testing, boilers & cooling towers, water treatment and more.
- Measures electrical conductivity (EC), total dissolved solids (TDS) and temperature.
- Three different calibration options (KCl, 442TM, NaCl), each with its own non-linear conversion factor.
- Automatic Temperature Compensation (ATC) using three temperature coefficients
- Waterproof housing
- Measurement Range: 0-9990 µS; 0-8560 ppm (auto-ranging).
- Digital Calibration (push button)
- Auto-off function, data-hold function and low-battery indicator.
- Display: large and easy-to-read LCD screen includes simultaneous temperature reading.
- Factory Calibrated: The COM-100 meter is calibrated with a 1413 µS solution. The meter can be recalibrated with digital calibration using the push buttons, rather than a screwdriver.
- Includes a cap, batteries and lanyard.
- EC Range: 0 - 9990 µS
- TDS Range: 0-8560 ppm (mg/L)
