pH / Redox (ORP) Sensor AP121

The pH / Redox (ORP) Sensor AP121 is a highly process-resistant 12 mm combination pH / Redox (ORP) electrode. It is equipped with a rugged solid electrolyte providing effective combat of process poisons and fluctuating pressures. The electrode has all three measuring elements located closely together and a very fast temperature response. This ensures high integrity of calibration and leads to tighter control. Already a number of years in service, the proven multi-pole VP connector facilitates easy connection and disconnection of multi-parameter sensor signals.
