EXtract 820M

plastics

Extract 820M is a manually operated retractable probe housing made of plastics to be attached on process tanks or tubing. The drive unit inserts the Sensor into the process medium and back into the cleaning chamber. When reaching the final position of the “measuring” or “service” position a safety knob locks each position automatically. Cleaning, rinsing and calibration of the sensor is possible while the process is running.
