- MOUNTING/POSITION -The unit/sensor should be mounted at chest height with the sample line travelling to the chosen target area at either maximum height for lighter than air gases or minimum low level (100mm) for heavier than air gases. A filter (Part no. 008-212) should be attached to the pipe end where high levels of particulates may be present.
