Features
Everything
Aér'Audits does
Two tools in one: a complete site survey module for auditing an air handling installation from A to Z, and a standalone flow/velocity/diameter calculator available at any time.
Main module
Installation site survey
Create one project per audited site. The project ID is generated automatically. Resume any existing audit at any time.
Automatic geolocation
City and altitude filled in automatically when opening a new project. Editable manually.
Resume an audit
All projects archived locally. Reopen a past audit to complete, modify or regenerate its report.
Integrated photos
Each piece of equipment accepts photos. Taken from the app or selected from the gallery. Included in the report.
Free-text comments
Every measurement point and every piece of equipment has a free multiline comments field.

Standalone tool
VQD Calculator
Accessible from the home screen without creating a project. Provide two of the three values — the app calculates the third.

Unknown flow rate
Enter velocity + diameter → flow rate in m³/h.
Unknown velocity
Enter flow rate + diameter → velocity in m/s.
Unknown diameter
Enter flow rate + velocity → duct diameter in mm.
Normalised flow rate
Add pressure (Pa) and temperature (°C) → automatic conversion to Nm³/h (0 °C / 101 325 Pa).
