Cleanfit COA451 is a retractable assembly for dissolved oxygen measurement in all fields. It is equipped with a locking bolt, O-rings and a ball valve that completely separate the sensor chamber from the process, allowing the sensor to be connected without interrupting the measurement or draining pipes and tanks. In addition, process and operational safety is increased and maintenance is effectively reduced throughout the entire measurement.
Benefits
Universal assembly for all kinds of applications: “one for all” optimizes inventory, accelerates project progress and simplifies life-cycle management
Simple and safe maintenance: sensor maintenance and cleaning without interrupting the process
Robust design: process pressures up to 10 bar (145 psi), up to 2 bar (29 psi) for manual operation
Convenient and time-saving operation: with rinse connection, sensor cleaning without removal
