YOKOGAWA PH CONVERTER PH402G-E-1-E

Description:

The Yokogawa PH402G-E-1-E pH/ORP Converter is used in industrial liquid analysis systems to measure pH and ORP values and convert sensor signals into standardized outputs for process control. Commonly installed in chemical plants, water treatment facilities, and industrial process systems where continuous liquid analysis is required. Maintenance teams, OEMs, and system integrators use this converter for process monitoring, replacement of legacy analyzers, and maintaining accurate pH/ORP measurement.

Applications:

The Yokogawa PH402G-E-1-E is used in industrial environments for continuous online measurement of pH and oxidation-reduction potential (ORP) in liquid processes. It is commonly deployed in wastewater treatment, chemical processing, food and beverage production, and power generation systems. The converter enables process control, alarm monitoring, and dosing/neutralization control, helping maintain product quality and safe operating conditions.
