Dwyer DM-1000 Series DigiMag Digital Differential Pressure Gauge
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.
- 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.
