This tester has automatic temperature compensation (ATC) and is water-resistant. Measurement range: 0–9990 µS; 0–5000 ppm; 0–9.9 mS; 0–5.0 ppt. Digital calibration (push button) to any point within the meter's range. Auto-off function, data-hold function and low battery indicator with large and easy-to-read LCD screen includes simultaneous temperature reading. Factory calibrated: The COM-80 meter is calibrated with a 1413 µS solution. The meter can be recalibrated with digital calibration using the push buttons. Includes a protective cap and batteries.
