Test Meters & Solutions » HM Digital

For optimal performance, re-calibrate your meters periodically or if testing TDS or conductivity levels in wide or different ranges.

• NaCl calibration solution.
• Comes in lightweight HDPE plastic bottles.
• Sealed with a coated foam liner.

• Measures electrical conductivity (EC), total dissolved solids (TDS) and temperature.
• Three different calibration options (KCl, 442TM, 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.
• 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.
• One year warranty.

• Measures pH and Temperature.
• Auto-ranging three point calibration with digital fine tuning.
• Includes 4 pH buffer solution in a sponge embedded in a clear cap.
• Waterproof housing.
• Simultaneous temperature display.
• Measurement Range: 0-14 pH.
• Digital automatic calibration (one point), with digital fine tuning.
• 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 PH-200 meter is three-point factory calibrated to 4, 7, and 10 pH. The meter can be recalibrated with digital calibration using the push buttons, rather than a screwdriver.
• Includes a cap, batteries, lanyard, and pH 7.0 buffer.
• One year warranty.
