China Probest PH Probe ORP Sensor with Dual Channels Transmitter
UNI20 Water meter could be with one channel or dual channels for your choice, UNI-20 Water quality meter is stable, and also with recorder for your choice.
The UNI-20 transmitter is highly versatile, and the existing digital and analog sensors from the company can be freely connected. Measurable parameters include pH, DO, ORP, Conductivity, Turbidity, SS, Chlorophyll, Blue-green algae, Residual chlorine, UVCOD, Ionic ammonia nitrogen, Nitrate nitrogen, Transparency and other parameters. UNI-20 can also choose single channel or dual channel configuration according to requirements. One transmitter can connect up to two sensors, reducing transmitter cost and installation space.
