Shop pH and ORP meters for measuring acidity, alkalinity and oxidation-reduction potential in water treatment, environmental testing, laboratories, industrial processes, pools and other water-quality applications.
Available instruments include portable, pen-style and probe-based meters for field measurements, process checks and routine water-quality testing.
pH meters measure the acidity or alkalinity of a solution, while ORP meters measure oxidation-reduction potential and can help evaluate chemical activity in water and process applications.
Important selection factors include measurement range, resolution, accuracy, electrode configuration, automatic temperature compensation, calibration method and whether pH, ORP or both measurements are required.
Replaceable electrodes and waterproof construction can be especially useful for routine field and water-treatment applications.
