l Pure water / drinking water / surface water / variety of water supply / industrial sewage.
l Acid, alkali and salt solution / chemical reaction process / industrial manufacturing process.
l Soilless cultivation / flower greenhouses / aquatic farming / swimming pool.
l Easy connect to PLC, industrial computer, controller, data logger or touch screen for online moniter and control.
l Dual high-impedance differential amplifier, strong anti interference, fast response.
l 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.
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 IP65 protection level.
