• Measures electrical conductivity (EC), total dissolved solids (TDS) and temperature.
• Three different calibration options (KCl, 442^TM, 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)
• Temperature Range: 0-80 °C; 32-176 °F
• Resolution: 0-99: 0.1 µS/ppm; 100-999: 1 µS/ppm; 1000-9990: 10 µS/ppm. Temp. resolution is 0.1 °C/F
• Accuracy: +/- 2%
• EC to TDS Conversion Factor: Non-linear conversions for KCl, 442^TM or NaCl solutions, set by the user.
