EXtract 811M

stainless steel, extended immersion

Extract 811M is a manually operated retractable probe housing made of stainless steel or Alloy to be attached on process tanks or tubing with an extended immersion length up to 207mm. 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.
