Product Description

PHG-203 industrial online pH transmitter

PHG-200 series two-wire industrial pH transmitter, composed bythe high-impedance electronics transformation unit and the glasselectrode, form the integration measure, display and transmission instruments. The PHG-200 transmitter is for online continuous detection of the solution's acid, alkalinity. It's applicable for chemical , oil refining, paper making, sugar refining, metallurgy, power generation, pharmaceutical and other industrial sectors in the production process or the sewage treatment process of continuous measurement and control.
  • Easy connect to PLC, industrial computer, controller, data logger or touch screen for online moniter and control.
  • Dual high-impedance differential amplifier, strong anti interference, fast response.
  • Patented pH probe, inner reference solution is promote by 250KPa pressure, extremely slow exudation. So that the potential is very stable long-termly, and  the lifetime of the reference electrode several times than normal industrial probe.
  • The probe use gold plate VP header for plug connection. Threaded fastening, very easy to replace the probe.
  • Easy mounting. The 3/4 NPT thread is easy for pipe and tank mounting. The probe can be also separated with the display header, connect by cable.
  • IP65 protection level.
