Cleanfit COA451 is a retractable assembly for all fields of dissolved oxygen measurements. It is equipped with a stop bolt, O-ring seals and a ball valve, enabling complete isolation of process and sensor compartment. This allows you to access the sensor without interrupting the process or emptying the pipe or tank. Better still, benefit from increased process and operational safety and significantly reduced maintenance effort across the whole measuring point.

Cleanfit COA451 is a retractable assembly for oxygen sensors with a diameter of 40 mm in:
