PH Transmitters, Brand Name : V-TECH

The pH Transmitter is an industrial-grade device designed for continuous monitoring and control of pH in various processes. It converts the signal from a pH electrode into a standard analog output (4–20 mA) compatible with PLCs, SCADA systems, and process control equipment.

The transmitter features automatic temperature compensation to ensure accurate readings over a wide temperature range. Multi-point calibration allows precise adjustment for standard buffer solutions (pH 4, 7, and 10). Models are available with local display options for real-time reading, as well as communication protocols like HART or Modbus for remote monitoring and integration into automation systems.

The rugged and corrosion-resistant housing ensures reliable operation in industrial environments, including chemical processing, water treatment, pharmaceuticals, and food & beverage industries.
