Dwyer DM-1102 Digital Differential Pressure Gauge
Product Introduction
The Dwyer DM-1102 DigiMag Digital Differential Pressure Gauge is a precision instrument designed for low-pressure monitoring in air and non-combustible gas systems. Part of the DM-1000 series, this gauge combines the reliability of the Magnehelic analog predecessor with digital versatility, making it ideal for isolation rooms, hospitals, and temporary installations where accuracy and ease of use are critical.
Product Features
Digital Versatility:
Field-programmable for pressure, air velocity, or flow measurements.
4-button interface for quick zero/span calibration and unit conversion (in. w.c., Pa, kPa, mBar).
Filter Maintenance Alert:
User-set dirty filter alarm with blinking display to prompt maintenance.
Dual Power Options:
9V battery (150-hour life at 1-second update) or 9–24 VDC for wired installations.
Battery backup ensures uninterrupted operation during power outages.
Rugged Design:
IP66 rating protects against dust and water jets, suitable for harsh environments.
