SERIES DM-1000

DIGIMAG® DIGITAL DIFFERENTIAL PRESSURE AND FLOW GAGE

24 Volt or Battery Powered, Fits in Magnehelic® Gage Cut-Out

CALIBRATION SERVICES AVAILABLE

PRESSURE

The Series DM-1000 DigiMag® Digital Differential Pressure and Flow Gage monitors the pressure of air and compatible gases just as its famous analog predecessor the Magnehelic

differential pressure gage. All models are factory calibrated to specic

ranges. The 4-digit LCD can display readings in common English and metric units so

conversions are not necessary. The simplied four button operation reduces set up time and simplies calibration with its digital push-button zero and span.

BENEFITS/FEATURES

• Field programmed reduces installation time

• User selectable parameters for pressure, air velocity or ow permits same device for

multiple applications

• Specialized lter set point for alerts when maintenance is due

• Security levels permit matches the correct access to right skill

• Power versatility works with 9-24 VDC or 9 V battery allows deployment in a variety of spaces wired or not

APPLICATIONS

• Differential pressure across lters

• Fan control

• Static pressures in ducts or buildings

• Room pressurization monitoring
