DESCRIPTION
In a hospital, laboratory or animal research facility, the
integrity of the ventilation control system is at the heart
of a contaminant free environment. Whether a room is
to be maintained at a negative pressure to prevent contaminants from escaping into adjacent areas or positive
pressure to protect patients with compromised immune
systems, the proper pressurization of the room is essential. To assure proper pressurization is maintained in
these critical environments, a room pressure monitor is
employed to measure and alert sta and personnel of
any change in pressure—no matter how small. A fail-safe
solution to monitoring these very low pressure changes is
Setra’s Model SRCM room pressure monitor, which utilizes
highly accurate capacitance sensing technology to measure and display true low pressure dierential.
