Dwyer DM-1122 : DigiMag Digital Minihelic II Differential Pressure Gage, Range 0 to ±0.25 in w.c., 4-digit LCD, NEMA 4X (IP66)
The Series DM-1000 DigiMag® Digital Differential Pressure and Flow Gauge offers precision monitoring for air and compatible gases, with factory-calibrated models for specific pressure ranges. Its user-friendly 4-digit LCD eliminates the need for conversions by displaying readings in both English and metric units. Featuring quick field programming, it reduces installation time and adapts easily to multiple applications, including filter monitoring, fan control, duct static pressure, and room pressurization. The customizable security levels ensure the right access for the right skill level, while versatile power options (9-24 VDC or 9V battery) allow installation in both wired and remote locations. With push-button zero and span calibration, setup and maintenance are streamlined for efficiency.
