H M Digital COM-100 Waterproof EC / TDS / Temperature Pocket Tester

This new and improved model from H M Digital offers easy, fast and effective EC, TDS and Temperature testing from a single unit.

With a modular design, things like the user replaceable electrode will ensure this unit is kept running hassle free for many years to come.

Ideal for all water quality testing, water purification applications, wastewater regulation, aquaculture, hydroponics, colloidal silver, labs & 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.

Main 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.
