Retractable Housings

N/ASL and 777-SL retractable housings for industrial processes will accept pH and ORP sensors containing liquid, gel or polymer electrolytes, as well as conductivity, DO and turbidity sensors. The design of the immersion tube (H=100 or 200 only) is said to guarantee complete separation of the process medium from the outside environment, independent of position. An additional safety device prevents the sensor from being removed when the housing is inserted in the measuring position.

The sensor detection system prevents insertion of the immersion tube into the process if no sensor is present in the housing. Standard immersion lengths are 70, 100 or 200 mm. All wetted parts are available in a choice of PVC, PVDF or stainless steel in order to satisfy individual process requirements.
