* 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.
* One year warranty.
