Control the WiFi model of Retrotec's DM32 digital pressure gauge wirelessly with the GaugeRemote app on Apple devices! GaugeRemote features the same intuitively designed user interface as the DM32 gauge itself, eliminating a learning curve for using the application. Simply launch the app and select the DM32 to connect to. A fully mirrored interface will allow you to set speed or pressure, change devices and ranges, and receive results.
IHWAP Diagnostics
This application assists with home weatherization by quantifying air leakage, calculating ventilation needs, and assessing duct system pressure against program standards. It helps prioritize air sealing and ensures compliance with energy efficiency guidelines.
- Zone Pressure Diagnostics (ZPD)
- Total External Static Pressure (TESP) calculation
- ASHRAE ventilation requirements
- Leakage reduction potential estimation
- ENERGY STAR compliance checks

Illinois Home Weatherization Assistance Program (IHWAP) Diagnostics application for the University of Illinois. This app is the product of a collaboration between the Indoor Climate Research & Training Center’s Senior Weatherization Trainer, Nate Price, and me. The Zone Pressure Diagnostics (ZPD) function will quantify the connection between the house and a zone and between that zone and the outdoors. It will also estimate the total leakage reduction potential in the zone, which should assist with prioritizing air sealing measures. The Total External Static Pressure (TESP) function will calculate total pressure and the pressure caused by the various components of a duct system and compare them to Illinois Home Weatherization Assistance Program (IHWAP) standards for recommended replacement options. The American Society of Heating and Air-Conditioning Engineers (ASHRAE) function will calculate home ventilation requirements ensuring proper pollutant control and ENERGY STAR compliance.
