Online Industry pH ORP Controller pH Transmitter
>>Overview
The Industrial Online pH/ORP Meter is a microprocessor-based water quality monitoring and control instrument. Configured with various types of pH or ORP electrodes, it is widely used in power plants, petrochemicals, metallurgy, electronics, mining, papermaking, bio-fermentation engineering, pharmaceuticals, food and beverage, environmental water treatment, aquaculture, modern agricultural cultivation, and other industries. It provides continuous monitoring and control of pH (acidity/alkalinity), ORP (oxidation-reduction potential), and temperature values in aqueous solutions.
