Sensor cleaning devices

There are a number of different sensor cleaning technologies which can be incorporated into your process application. Generally these include water jet cleaning, physical brush cleaning, ultrasonic cleaning and/or chemical cleaning procedures or a combination of these.

The cleaning options are mainly divided into two types. Those for the immersion series sensor (HC-7) and then those for the flow thru sensors (HC-8)

The available model and type of cleaning devices are as follows:.

- BHC-7B Immersion sensor / Brush cleaning (pdf)
- JHC-7B Immersion sensor / Water jet cleaning (pdf)
- BJHC-7B Immersion sensor/ Brush and water jet cleaning (pdf)
- RHC-7A Immersion sensor / Chemical/Reagent cleaning (pdf)
- BRHC-7A Immersion sensor / Brush and Reagent cleaning (pdf)
- UHC-7B Immersion sensor / Ultrasonic cleaning (pdf)

- UHC-8A Flow thru sensor / Ultrasonic cleaning (pdf)
- JHC-8A Flow thru sensor / Water jet cleaning (pdf)
