Hospi-Gard® Room Pressure Monitor

The Hospi-Gard® Room Pressure Monitor installs easily on any wall and can be used for both positive and negative pressure rooms. The unit performs reliably at low room pressures and has a sensitivity of 0.001 w.g. (0.25 PA) The green or red status light indicates positive or negative room pressure. The pressure at which the light changes from positive to negative can be adjusted from the front panel.

The standard SPDT relay can be connected to an audible alarm or remote status indicator. Three analog output signals with ranges from 0-5 Vdc, 0-10 Vdc and 4-20 Vdc are proportional to the room pressure.
