Dwyer RSM-5-B Room Status Digital Pressure Gauge

Product Introduction

The Dwyer RSM-5-B Room Status Digital Pressure Gauge is a high-accuracy instrument designed for critical low differential pressure monitoring in environments requiring strict safety and compliance. With a measurement range of ±1" w.c., this gauge is ideal for hospital isolation wards, pharmaceutical facilities, and clean rooms, adhering to CDC guidelines for pressure control. It features a graphic user interface for intuitive access to pressure data, calibration settings, and alarm configurations, housed in a NEMA 1 (IP20) fire-retardant plastic enclosure for indoor use. The RSM-5-B supports selectable output signals (4–20 mA, 0–5 VDC, 0–10 VDC) and optional BACnet communication for seamless integration with building automation systems.
