DESCRIPTION
In a pharmaceutical, hospital, laboratory, or animal research
facility, the integrity of the ventilation control system is at the
be maintained at a positive pressure to prevent product con-
tamination or a negative pressure to prevent contaminants
from escaping into adjacent areas, 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 mat-
ter how small. A fail-safe solution to monitoring these very low
pressure changes is Setra’s Model SRIM room pressure monitor,
which utilizes highly accurate capacitance sensing technology
to measure and display true low pressure dierential.
