Dwyer DM-1000 DigiMag Digital Differential Pressure Gauge

Dwyer DM-1000 Series DigiMag Digital Differential Pressure Gauge

Product Introduction

The Dwyer DM-1000 Series DigiMag Digital Differential Pressure Gauge is a versatile instrument designed for precise measurement of differential pressure, air velocity, and flow for air and non-combustible gases. Equivalent to the Magnehelic gauge in functionality, it features a 4-digit LCD display with selectable Imperial/Metric units and intuitive 4-button controls for easy calibration. Field-programmable for pressure, velocity, or flow modes, the DM-1000 can be set to flash alerts for filter maintenance, track peak/valley data, and adjust display updates—making it ideal for HVAC, clean room, and industrial filtration applications.

Product Features

Multi-Function Measurement:

Differential pressure, air velocity, and flow rate (with pitot tube/K-factor settings).

Filter clogging alerts via display flashing for maintenance scheduling.

Precision & Stability:

±1% FS accuracy (±2% for ranges ≤1" w.c.) with ±1% FS/year long-term stability.

Temperature compensation (32–122°F/0–50°C) for consistent readings.

Flexible Display & Units:

4-digit LCD (0.60"H digits) with update intervals (1 sec–10 min) or button-triggered updates.

Selectable units: in w.c., psi, kPa, mm w.c., mBar, etc.

Power & Durability:

9V battery (1.5-year life in standby) or 9–24 VDC external power.

NEMA 4X (IP66) fiberglass housing for dust/water protection.

User-Programmable Functions:

Security level settings, K-factor calibration for flow sensors, data smoothing, and zero-to-full span adjustments.
