SERIES DM-1000

DIGIMAG® DIGITAL DIFFERENTIAL PRESSURE AND FLOW GAGE

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

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 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.

FEATURES/BENEFITS

• 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

• Filter monitoring

• Air velocity or ow

• Blower vacuum monitoring

• Fan pressure indication

• Duct, room or building pressures

• Clean room positive pressure indication
