The maintenance free Polyplast Pro RX sensor is designed for ORP measurement in water applications and low
conductivity samples, e.g. wastewater, fish farming, ground water, etc.
The Single Pore liquid junction guarantees best measurement results because of direct
contact between the sample and the Polisolve electrolyte – clogging is nearly impossible.
The Polyplast Pro RX comes with a robust plastic shaft and glass bulb protection, making it one of our most economical and longest lasting sensors.
