low cost ph meter
1. Typical applications
PHG***1: For PH on line measurement of swimming pool, aquatic farming, flower greenhouses, soilless cultivation and etc, very cost efficient.
2. Instrument characteristics
l Multiple signal output is optional: ***0mA(2 wire analog), **2V(analog), Rs**5(Modbus/RTU, digital).
l Easy connect to PLC, industrial computer, controller, data logger or touch screen for online monitor and control.
l Dual high-impedance differential amplifier, strong anti interference, fast response.
l Patented pH probe, inner reference solution is promote by at least **0KPa 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.
l The probe use gold plate VP header for plug connection. Threaded fastening, very easy to replace the probe.
l 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.
l IP*5 protection level.
