EXtract 815M

stainless steel for welding socket DN25

EXtract 815M is a manually operated retractable probe housing made of stainless steel or Alloy to be attached on process tanks or tubing by welding sockets DN25. 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. The innovative design provides maximum safety and easy operation. An integrated PTFE scraper allows the use even in rough processes.
