Sensor Cleaning with the Retractex BC

Once retracted, the sensor can be cleaned while the process is running. Cleaning fluid is connected through external ports where either manual cleaning or automated cleaning with the RetractoControl can occur.

A PTFE scraper with o-ring built into the insertion tube guarantees that process build-up stays outside of the armature and does not harm the internal o-ring seals.
