The DM32 WiFi

Digital Pressure Gauge

The DM32 WiFi is a dual channel touchscreen (wireless optional) manometer /differential pressure gauge for Blower Door and DucTester operation.

It’s small, lightweight, and exceptionally intuitive to use. It can be controlled with a computer (MS Windows only) or any Android or iOS smart device. DM32 WiFi can be connected via WiFi, Ethernet, or USB. Ethernet cables of 100 m / 328 ft segments can be used, offering an unlimited distance of reliable control, without the need for pressure tube extensions.

Included with the DM32 WiFi is a package of analytical software, developed exclusively for the DM32 WiFi, to equip testers with the most comprehensive tools available to collect, export, and evaluate air leakage testing results

New DM32 WiFi features developed in the future can be updated easily onto the gauge from the internet.

DM32 features:

  • 3.2” color touchscreen
  • Pre-calibrated digital pressure sensors with a new 5 year calibration schedule
  • Visual Display of “Device” and “Range”
  • High capacity (4200 mAh) rechargeable battery (Lithium polymer)- test for 10 hours on a single charge
  • Color coded tapered tube connections don’t leak and allow easy release
  • Test at any pressure
  • WiFi optional - run a test wirelessly from your smartphone or tablet!
  • Wired (Ethernet or USB) networking capability
  • Software for automatic test control, data acquisition, and remote control and monitoring with a virtual simulator on PC (MS Windows only).
  • Free online updates
  • Standard USB charger

Supported Units of Measurement and Results

Channel A:

Pressure: Pa, psf, or in WC

Channel B:

Pressure: Pa, psf, or in WC

Flow:  CFM, L/s, m3/s, m3/h

Flow/Area (Permeability):  CFM/sq ft, CFM/100 sq ft, CFM/1000sq ft, (m3/h)/m2, (L/s)/m2

Air changes per hour:  /h

Equivalent leakage area,  “EqLA”: sq ft, sq in, cm2

Effective leakage area,  “EfLA”: sq ft, sq in, cm2

*Results can be extrapolated to any desired test pressure

The following results are already extrapolated to the stated reference pressure:

  • Equivalent leakage area extrapolated to 10 Pa, “EqLA10”:  sq ft, sq in, cm2
  • Equivalent leakage area per enclosure area at 10 Pa,  “EqLA10/area”: sq ft/sq ft, sq in/sq ft, sq in/100sq ft, cm2/m2)
  • Effective leakage area extrapolated to 4 Pa,  “EfLA4”: sq ft, sq in, cm2
  • Effective leakage area per enclosure area at 4 Pa, “EfLA4/area”: (sq ft/sq ft, sq in/sq ft, sq in/100sq ft, cm2/m2)
