Insect Guard PIR 7000
*)
(Part no. 68 11 609)
Hydrophobic Filter PIR 7000
**)
(Part no. 68 11 890)
Intended use:
— The hydrophobic filter is designed to protect the measuring cuvette in applications with
extreme dust or dirt accumulation.
Dust and dirt particles can settle on the optical surfaces of the gas transmitter thereby
resulting in an early malfunction.
— The hydrophobic filter must only be used in combination with status indicator PIR 7000 /
7200 (part no. 6811625/6811920), the flowcell PIR 7000 / 7200 (part no. 6811490/
6811910) or the bump test adapter PIR 7000 / 7200 (part no. 6811630/6811930).

The insect guard PIR 7000 is also suitable for the use with Dräger PIR 7200.
Intended use:
— The insect guard is designed to prevent
insects from blocking the gas inlet and
outlet apertures as well as the inner gas
passages in the splash guard.
Mounting:
● Slot both parts of the insect guard into
the openings of the splash guard.
NOTICE
Using the insect guard lengthens the
response time of the gas transmitter, see
"Performance Characteristics (typical
values)" on page 73.
