1.0 INTENDED USE
The SRPM is designed to monitor critical environments by providing
differential pressure indication. Typically this is between a monitored
room and a reference space such as a corridor or ante room. The unit
also provides monitoring, alarm and communications functions.
Installation must be indoors, Polution Degree 2, Installation Category II.
Typical Applications:
1. Hospitals – patient isolation and protection rooms, operating
suites, intensive care, and emergency rooms.
2. Pharmaceutical, semiconductor, precision manufacturing, and
clean rooms.
3. Laboratories – medical research, BSL (Bio safety labs), radiation,
vivarium, toxic metals and chemicals. Indoor use only.
