Cleaning the Holder
When process fluid contains slurry which tends to settle in the holder regularly so that the slurry
does not build up. Remove the plug or cleaning element on the holder bottom to clean the holder.

Inspecting the O-ring Seal
The O-ring seal used in the wetted part of the flow-through type holder is made of fluorocarbon
rubber, which has superior resistance to corrosion - suitable for use with most process fluids.
Usually, therefore, no periodic inspection is necessary. When a flow-through holder with
ultrasonic cleaner is used, if the process fluid enters the ultrasonic cleaner, parts replacement
may be required to repair it. Inspect the O-ring seal when checking or repairing the ultrasonic
cleaner.
To prevent trouble, replace the O-ring seal periodically - e.g. every two years.
