Pressurized Housings
Pressurized housings are used with the refillable ChemoTrode sensors. The pressurization ensures a constant outflow of electrolyte which helps to prevent clogging of the diaphragm and poisoning of the electrolyte. It can be used in a large variety of applications in the chemical industry.

Masterfit
A static housing with G 1¼" process connection and multiple insertion depths to accommodate processes up to 6 bar.

RetractoMaster
All the advantages of refillable sensor technology can now be paired with a manually retractable housing.

What is a refillable sensor and why would I choose it?
Refillable sensors have a port that allows manual replenishment of the reference electrolyte. Processes like pure water leach out out the electrolyte so the Ionotrode is a good choice. Other products like the ChemoTrode allow the for externally pressurized electrolyte so the process liquid cannot easily contaminate the sensor. -
What is A-length and how is it measured?
A-length refers to the insertion depth of the sensor. It's generally measured from the base of the PG13.5 mounting threads but can vary with certain styles of sensors. -
