Features

• Measures electrical conductivity (EC), total dissolved solids (TDS), salinity and temperature
• Upgraded; four scales: µS, mS, ppm, ppt (mS and ppt are new)
• Three different non-linear EC-to-TDS conversion factors (KCl, 442TM, NaCl)
• Automatic temperature compensation (ATC) using three temperature coefficients
• Waterproof housing (IP-67 rating)
• Measurement range: 0 - 9,990 µS; 0-8,560 ppm; 0-9.99 mS; 0-8.56 ppt
• 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-C1)
• 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
