Mounting the protective hood
CH cleaning head
(option)
For permanent operation, we recommend to use the CH cleaning head
for compressed air-driven cleaning. It is mounted instead of the
standard protective hood. The compressed air cleaning is started time-
controlled via the IQ S
ENSOR
N
ET
system. Information on the required
components is given in the YSI catalog and on the Internet.
If no CH cleaning head is used the standard protective hood should
always be mounted for measuring. It protects the electrodes from rough
mechanical impact.
