7. For internal use only !! Cross sensitivity SF6-LeakPointer 3-033-R002
SF6-LeakSpy
3-033-R200/201
Moisture
Sensitive to moisture;
reacts to humid breathing air (= air moisture) and in head space of liquids
No cross-sensitivity to moisture (0 – 100 % rM not conden-sating)
VOCs and other gases
Reacts to all substances that impair ionisation.
Virtually no cross-sensitivity to other gases by using a narrow-band optical filter.
Background contamination
Sensitive to environmental influences and other gases
No sensitivity to background contamination (can be adjusted to the SF6 value encountered).
Impact of large leakages
Uneffected by large leakages and 100 % SF6
