A Focus on Simplified Air Tightness Testing and Report Generation 

TEC Auto Test is an automated building and duct system airtightness testing app for mobile devices. The TEC Auto Test app allows the user to make a wireless connection via Bluetooth or Wi-Fi with a DG-1000 or Wi-Fi with a DG-700 & WiFi Link to conduct an automated airtightness test of a building or duct system.

  • Collects the required test data from the connected gauge (and flow device)
  • Calculates and immediately displays test results.
  • Creates PDF test reports for viewing and sharing via email or cloud sharing apps
  • Project files can be geotagged using location services on your mobile device
  • Available for iOS and Android devices
  • Simplified connection using Bluetooth with DG-1000 leaves Wi-Fi available for other use when on-site
  • Supports both building and duct system airtightness tests.
