Cautions during handling
An extremely thin membrane is stretched across the DO
tip and DO responsive part. Do not allow the membrane
to be in contact with any hard surface and do not exert
undue force on the diaphragm.
When attaching the DO tip to the electrode body, check
to make sure that O-ring is attached. Attach the DO tip
securely to the electrode body.
DO tips that are no longer usable should be disposed of
as industrial waste.
