Ideal for all water quality testing, RO/DI, aquariums, water purification applications, wastewater regulation, aquaculture, hydroponics, colloidal silver, labs & scientific testing, pools & spas, ecology testing, boilers & cooling towers, water treatment and more.

FEATURES:

• Measures electrical conductivity (EC), total dissolved solids (TDS) and temperature.
• Three different calibration options (KCl, 442^TM, NaCl), each with its own non-linear conversion factor.
• Automatic Temperature Compensation (ATC) using three temperature coefficients
• Waterproof housing (IP-67 rating)
• Measurement Range: 0-9990 µS; 0-8560 ppm (auto-ranging).
• Digital Calibration (push button)
• Auto-off function, data-hold function and low-battery indicator.
• Display: large and easy-to-read LCD screen includes simultaneous temperature reading.
• 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.
