NOTICE!
Maximum permissible operating pressure of in-line
probe housing
Limit the pressure to a maximum of 2 bar (at 30 °C)
directly at the sample water extraction point using a
pressure reducer, otherwise the maximum permissible
operating pressure of the in-line probe housing will be
exceeded.
Do not allow a back pressure of more than 2 bar
(at 30 °C) to build up at the outlet, otherwise the max‐
imum permissible operating pressure of the in-line
probe housing will be exceeded.
