The Setra Model SRPM Room Pressure Monitor is designed for accurate monitoring and alarming of low differential pressure in critical environments such as isolation rooms and cleanrooms. It supports positive, negative, or neutral pressure monitoring and features a touchscreen RGB LCD display with intuitive menus for setup, calibration, and security. A dead‑ended capacitive pressure sensor prevents cross‑contamination and long‑term drift. Red and green visual indicators, a local audible alarm with delay, and optional BACnet® MS/TP communication make the SRPM a complete, reliable room pressure solution.
