The Cleanfit CPA871 ensures maximum operating safety in standard and demanding applications. Its intelligent functions prevent any medium leakage during operation, cleaning or calibration, providing optimal protection for the process and operating personnel. The retractable assembly flexibly adapts to your application conditions. With long insertion depths in viscous media, corrosive environments or hazardous areas, selecting the right material and specifications ensures your application requirements are met.
Benefits
Maximum operating safety: intelligent functions prevent the assembly from being moved into the process without a sensor and prevent the sensor from being removed at the measuring position.
Suitable for demanding applications: optional immersion chamber eliminates problems caused by viscous media.
Rugged assembly design: steel base housing ensures mechanical stability.
Flexible adaptation to process conditions: wide range of process connections and wetted-part materials, even for corrosive media or hazardous areas.
Application areas
The Cleanfit CPA871 is a retractable assembly for installing pH electrodes, ORP electrodes, dissolved oxygen sensors and NIR sensors with a diameter of 12 mm and lengths of 120/225/360 mm.
