COM-100 EC / TDS / Temp Meter Combo

COM-100 - EC/TDS/Temp Meter Combo This HM digital meter measures electrical conductivity (EC), total dissolved solids (TDS), and temperature. UPGRADED!! (See below) Ideal for all water quality testing, water purification applications, wastewater regulation, aquaculture, hydroponics, colloidl silver, labs and scientific testing, pools & spas, ecology testing, boilers & cooling towers, water treatment and more. The COM-100 is a professional level EC/TDS meter at an unbeatable price. Standard Features   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: 0-9990 µS; 0-8560 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. See how the COM-100 stacks up against the competition.
