Digital differential pressure gauge for HEPA ZONE 24 portable work enclosure (SAH12). Sold individually.
A differential pressure gauge displays the atmospheric pressure difference before the HEPA filter (including the enclosure cabin and any plenum space accessed during work) and after the HEPA filter (outside the cabin).
With the work enclosure air scrubber running, the differential pressure gauge confirms that the cabin is under negative pressure with respect to its surroundings. This ensures that all dust, spores and airborne particulates will not blow out of the enclosure until they are trapped by the HEPA filter.
