HM COM-100, Waterproof Handheld Water Conductivity Meter and TDS Meter

HM COM 100 portable conductivity meter is Ideal for all water quality testing, water salinity testing, water purification applications, RO Systems, wastewater regulation, aquaculture, hydroponics, colloidal silver, labs & scientific testing, pools & spas, ecology testing, boilers & cooling towers, water treatment and more. The HM COM-100 is a professional level EC/TDS meter at an unbeatable price.

EC Meter / TDS Meter Features:

- Backligh 4 Digit Disply.
- COM100 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.
- Manfacturer: HM Digital (Korea).
- Includes a cap, batteries and lanyard.
