- HM Digital COM-100 Waterproof EC, TDS Tester with Thermometer:
- The COM-100 is ideal for all water quality testing, water purificationapplications, wastewater regulation, aquaculture, hydroponics, colloidal silver,labs and scientific testing, pools and spas, ecology testing, boilers andcooling towers, water treatment and more.
- The Waterproof COM-100 tester measures electrical conductivity (EC), total dissolved solids (TDS), salinity and temperature.
- This upgraded tester has four measurement scales: µS, mS, ppm, and ppt (mS and ppt are new).
- This water tester has three different non-linear EC-to-TDS conversion factors (KCl, 442TM, NaCl).
- The COM-100 has Automatic Temperature Compensation (ATC) using threetemperature coefficients.
- This combo meter comes with a waterproof housing (IP-67 rating).
- Measurement range of the COM-100: 0-9990 µS; 0-8560 ppm; 0-9.99 mS; 0-8.56 ppt.
- This combo meter can be digitally calibrated with a push button to any point within it's range.
- This waterproof tester COM-100 has an auto-off function, data-hold function and low-battery indicator.
- Display: Large and easy-to-read LCD screen includes simultaneous temperature reading.
- The Sensor for this Waterproof Combo Meter is replaceable with the SP-C1 sensor.
- 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.
- A cap, batteries and lanyard are included.
