portable ph meter

portable ph meter 1.pH range:0-14pH,ORP:-1500 ~1500mV 2.Accuracy: +-0.03PH,+-3mV 3.Power supply:DC24V                                         portable ph meter  PHG series of two-wire industrial  ph sensor PHG-200 series two-wire industrial pH transmitter, composed by the high-impedance electronics transformation unit and the glass electrode, 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. 

Features

   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.
