BGC-FTIR Sensors | KPC 1/6-ME 9
Maintenance
The protective filter should only be screwed off carefully to check functioning
with a humidity standard. Take care not to touch the highly sensitive sensor
element. If necerssary, the soiled sintered filter can be screwed off and rinsed.
When you screw them back on, bear in mind that the sensor will not meassure
accurately again until everything is completely dry. For ballancing the offset
after calibration see section 1.3.3 on page 39.
Mounting
The weather guard can easily be mounted on the mast on top of the BGC-
FTIR-Container. It has to be pointed out that there is a difference in height
because of the construction of the clamps.

NOTE: Take care not to damage the sensing elemet when screwing-off the
filter.
