Portable pH Water Quality Tester

The portable pH water quality detector uses a glass electrode and a reference electrode to form a galvanic cell, measuring the potential difference generated by the hydrogen ion concentration in the water sample, which is then converted into a pH value by the circuit. It is used for rapid on-site detection of water acidity and alkalinity, and is suitable for environmental monitoring, aquaculture, wastewater treatment, and other fields.
Selection
When selecting, focus on a measurement range that covers common water pH levels, with accuracy meeting detection requirements. The electrode material should be corrosion-resistant and feature temperature compensation. Check the calibration method and data storage capabilities, consider the instrument's protection rating and battery life, and choose a suitable model based on actual usage scenarios.
