The WXZJ-ORP20A Industrial ORP Meter is a microprocessor-based online water quality monitoring instrument. Equipped with various types of pH (or ORP) electrodes, this device is widely used in power plants, petrochemicals, metallurgy, electronics, mining, papermaking, bioprocessing, pharmaceuticals, food and beverage, environmental water treatment, and other industries for continuous monitoring and control of the acidity/alkalinity (pH), ORP value, and temperature of aqueous solutions. Applications include power plant feedwater, saturated water, condensate, general industrial water, domestic water, and wastewater.

The complete measurement system mainly consists of the instrument (secondary device) and the ORP electrode (primary device). The ORP electrode contacts the measured aqueous solution, while the instrument displays the ORP value, temperature, and operational status of the solution.
