Digital pH Meter

The Digital pH Meter provides laboratory-grade pH measurement in a compact, waterproof housing suitable for direct immersion in aquarium water. The glass combination electrode delivers readings to two decimal places with ±0.01 pH accuracy after calibration, far exceeding the resolution of liquid test kits or test strips.

Automatic temperature compensation (ATC) adjusts the millivolt-to-pH conversion in real time as water temperature changes between 0°C and 60°C, ensuring readings remain accurate without manual correction. The large backlit LCD displays both pH and temperature simultaneously, and the auto-off function extends battery life during infrequent use.

The meter supports two-point calibration using pH 4.01 and pH 7.00 buffer solutions. The glass probe is replaceable, extending the service life of the meter body. Suitable for freshwater, brackish, and marine aquariums.
