Dwyer DM-1103 Digital Differential Pressure Gauge with LCD Display

The Dwyer DM-1103 is a high-precision digital differential pressure gauge designed for measuring air and non-combustible gas pressures. This advanced instrument replaces traditional analog Magnehelic® gauges with enhanced functionality and digital precision.

• Precision Measurement: ±1% FS accuracy (at 32-122°F/0-50°C), ±2% for ultra-low ranges (≤1" w.c.)
• Versatile Display: 4-digit LCD with selectable update intervals (1 sec-10 min) or manual update
• Multiple Units: Displays in w.c., psi, kPa, mBar, mm Hg, and more - eliminating manual conversions
• Dual Power Options: 9V battery (150 hours @1 sec update) or 9-24 VDC external power
• Programmable Modes: Field-configurable for pressure, velocity, or flow measurements
• Maintenance Alerts: Filter clogging alert (display blinking) at user-set thresholds
• Rugged Construction: NEMA 4X (IP66) enclosure for dust/water protection in harsh environments

Ideal for critical environment monitoring in HVAC systems, cleanrooms, laboratories, and industrial processes where precise differential pressure measurement is essential.
