Today's building performance test procedures require diagnostic tools that are versatile, accurate and easy to use. The Energy Conservatory combines all these qualities into an advanced line of hand-held digital gauges that give you the power and flexiblility to handle all types of building performance investigations.


DG-700 Pressure and Flow Gauge

The new DG-700 Pressure and Flow Gauge is a multi-functional differential pressure gauge with 2 independent pressure sensors. In addition to providing high-resolution pressure measurements, the DG-700 is programmed to operate with other Energy Conservatory test devices to provide air flow measurements during building performance test procedures. The DG-700's simultaneous display of two pressure channels and air flow measurement features make it ideally suited for a wide range of building performance applications including airtightness testing of buildings and duct systems, air handler flow measurements, building depressurization and combustion safety testing.

DG-700 Features:

  • Simultaneous display of 2 independent differential pressure channels.
  • Bi-directional, precision pressure measurement up to 1,250 Pa (5" w.c.). The DG-700 can display pressure readings in both Pascals and " w.c.
  • Auto-zeroing of both channels eliminates sensitivity to orientation and temperature, making it perfect for hand-held operation.
  • Four separate time-averaging modes (1, 5, 10 second & long-term) allow you to accurately measure fluctuating pressures.
  • Programmed to display air flow readings for Minneapolis Blower Door and Duct Blaster systems, TrueFlow Air Handler Flow Meter and Exhaust Fan Flow Meter (air flow units can be displayed in cubic feet per minute, cubic meters per hour and litres per second).
  • "Baseline" feature allows the user to measure and record a baseline pressure reading, and then display the baseline adjusted reading.
  • The Cruise Control feature allows you to control a Blower Door or Duct Blaster fan to maintain a constant 75, 50, 25 or 0 Pa test pressure without connection to a computer.
  • The DG-700 includes both a USB and RS-232 port that can be used along with a computer and specialized TEC software to conduct fully automated Blower Door tests (TECTITE software), and for data logging of pressure measurements from both channels (TECLOG software).
  • Programmed to display velocity measurements using a Pitot tube (velocity units can be displayed in both feet per minute and meters per second).

DG-500 Pressure Gauge

The DG-500 is a high resolution differential pressure gauge with simultaneous display of two independent measurement channels. The DG-500 can be used along with a computer and specialized software to record and graphically display pressure measurements from both channels, making it ideal for diagnosing pressure problems in buildings.

DG-500 Features:

  • Simultaneous display of 2 independent differential pressure channels.
  • Bi-directional, precision pressure measurement up to 1,250 Pa (5" w.c.). The DG-500 can display pressure readings in both Pascals and " w.c.
  • Auto-zeroing of both channels eliminates sensitivity to orientation and temperature, making it perfect for hand-held operation.
  • Four separate time-averaging modes (1, 5, 10 second & long-term) allow you to accurately measure fluctuating pressures.
  • Programmed to display velocity measurements using a Pitot tube (velocity units can be displayed in both feet per minute and meters per second).
  • A HOLD button temporarily freezes the most recent display readings.
  • The DG-500 can be used along with a computer and specialized TEC data logging software (TECLOG) to record and graphically display pressure measurements from both channels.
