Product Specification

PHG-202 Online pH Transmitters Application environment

• For acid / base / salt solution, chemical reactions, industrial processes, it is possible to meet the most demanding requirements of industrial applications online PH measurement.
• Signal output: RS485 (Modbus / RTU protocol).
• Easy connection to a PLC, DCS, industrial control computer, universal controller, paperless recording instruments or touch screen and other third-party devices.
• Dual high-impedance differential amplifier, strong anti-jamming, fast response.
• The patented pH probe, the internal reference at least 100KPa (1Bar) pressure than the extremely slow oozing fluid from the porous salt bridge, the forward oozing continued for 20 months. Such a system is very stable reference electrode life more than doubled to extend common electrode industry.
• Easy Installation: 3/4 inch NPT (pipe thread) for mounting on pipes and tanks. Probe and a display portion can be separated via a cable connection.
• IP68 protection grade.
