Dwyer DM-1000 Series DigiMag Digital Differential Pressure and Flow Gages

Product Introduction

The Dwyer DM-1000 Series DigiMag Digital Gages redefine precision pressure and flow monitoring for air and compatible gases, offering a digital upgrade to the iconic Magnehelic analog gauges. Factory-calibrated for specific ranges, these gages feature a 4-digit LCD that displays readings in both imperial and metric units, eliminating conversion needs. With versatile power options (9–24 VDC or 9V battery), they ensure continuous operation, even during power interruptions. The user-friendly four-button interface enables quick programming for pressure, air velocity, or flow measurements, while advanced features like filter maintenance alerts and digital damping make them ideal for industrial and commercial applications.

Product Features

Digital Precision & Versatility:

4-digit LCD with selectable engineering units (in w.c., Pa, m/s, cfm) for real-time, conversion-free readings.

Full-scale accuracy: 1% for ranges ≥2 in w.c., 2% for low ranges (0.25–1 in w.c.).

Programmable Functionality:

Field-selectable modes for pressure, air velocity, or flow (depending on model).

Filter set point alert (blinking display) for maintenance scheduling in dirty filter scenarios.

Power Flexibility:

9–24 VDC line power or 9V battery operation; battery acts as backup during power outages.

Intuitive Operation:

Four-button menu system for easy access to security settings, K-factor programming, duct sizing, and peak/valley tracking.

Digital damping to smooth erratic readings and display update controls for battery conservation.

Retrofit Compatibility:

Fits standard Magnehelic gauge cut-outs for seamless analog-to-digital upgrades.

Robust Design:

Engineered for air and non-corrosive gas applications, with pressure ranges from 0–0.25 in w.c. to 0–100 in w.c.

Application Suitability:

Filter monitoring, air velocity/flow measurement, blower vacuum, clean room pressure, and HVAC systems.
