COM-100 TDS Water Meter

COM-100 Waterproof EC TDS + Temperature combo Water Tester. 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. This Electronic Water Tester can measure Total Dissolved Solids (TDS) in water and Temperature.

COM-100 TDS Water Meter 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
• 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.
• The COM-100 water meter is calibrated with a µS solution. The meter can be recalibrated with digital calibration using the push buttons, rather than a screwdriver.
• Includes a cap, batteries and lanyard.
   
• HM Digital TDS meters come factory calibrated and are ready to use. They are designed to stay consistent. However, after prolonged usage, it may help to recalibrate your meter using a commercial standard NaCl-based solution, which is approximately, 0.5 µS of conductivity.
   
• Immerse the meter into the calibration solution. If the meter does not read within 2% of the calibration solution, adjust the reading by inserting a mini screwdriver (not included) into the trimmer pot (the hole on the back of the meter). Turn the trimmer clockwise to increase the reading and counterclockwise to decrease the reading. Note that the adjuster is very sensitive.
