Reliable in Demanding Applications
The InPro2000i refillable pH sensor uses a pressurizable reference electrolyte that ensures permanent self-cleaning of the diaphragm. This leads to long-term pH measurement stability and low maintenance in harsh applications.

Improved Junction Cleaning
This refillable pH/ORP sensor uses a 9823 3M KCl electrolyte. This classic electrolyte offers a high outflow for improved diaphragm cleaning. This helps to ensure a consistently reliable measurement without the need for sensor cleaning.

Meets Your Installation Requirements
The InPro 2000i SG/120/9823 has an integrated digital temperature signal for reliable temperature compensation. With a length of 120 mm, it's optimal when short installations are needed.

Accurate, Reliable Measurement System
The InPro 2000i is designed with long-term accuracy and reliability in mind. It is sterilizable and autoclavable, has an Argenthal silver-ion trap to prevent sulfide poisoning of the junction, and is ATEX and FM certified for installation in hazardous areas.
