HM Digital pH Hydrotester Meter

The HM Digital pH HydroTester is a reliable pH meter that is ideal for testing applications such as hydroponics and gardening, pools and spas, aquariums and reef tanks, water ionizers, drinking water and more. The sleek, lightweight design is water-resistant, features one-touch automatic digital calibration, measures temperature, has automatic temperature compensation (ATC) and an LCD screen. This tester includes storage solution in a sponge embedded in a translucent cap, pH 7.0 buffer and batteries. This product carries a one-year warranty.

• Uses 3 1.5V button cell batteries (included)
• Includes a 20 ml package of pH 7.0 buffer solution
• Measures pH and temperature (C/F)

Calibrate the meter with fresh buffer according to the instructions before relying on a new series of readings. Rinse the electrode between samples, blot rather than rub it, and allow the temperature-compensated value to stabilize. Keep the sensing bulb moist with the specified storage solution; distilled water is for rinsing, not long-term electrode storage. Periodically compare readings with known buffer and replace batteries or service the probe when calibration becomes slow or unstable.
