AP121
Brand: ABB GroupThe AP121 is a highly process-resistant 12 mm combination pH / redox (ORP) electrode.
It is equipped with a rugged solid electrolyte providing an effective shield to process poisons and fluctuating pressures.
The electrode has all 3 measuring elements located closely together and a very fast temperature response.
This ensures high integrity calibration and tighter control.
Already a number of years in service, the proven multi-pole VP connector enables easy connection / disconnection of multi-parameter sensor signals.
Features- Exceptional resistance to poisoning and pressure
- IP67 (NEMA 6P) ingress protection
- High corrosion resistance and steam sterilizability
- Assured high accuracy of calibration and operation
- Rapid response enabling tighter process control
- Unparalleled resistance to plugging
- Extended life and improved performance
