Users can read the measurements using the testo Smart Probes app installed on their smart device. The app lets users configure duct dimensions to calculate volume flow measurements. Use the testo 405i along with the testo 605i thermo-hygrometer to determine cooling and heating performance. The testo 405i works on smart devices with either Android or Apple operating systems.
The testo 405i Smart Probe is a wireless instrument for measuring air flow velocity, temperature, and volume flow. It is equipped with a telescopic shaft, which extends to 15” for easy in-duct testing. You can reliably determine timed and multipoint flow traverses.
All measurement data is displayed as instrument readings, tables, or graphs. The measurements can be quickly saved as PDF or Excel files. The app creates custom reports, which can be saved and/or shared by email. All your data can be stored and retrieved, saving you hours of time consuming paperwork!
Requires iOS 8.3 or newer; requires Android 4.3 or newer; requires mobile end device with Bluetooth 4.0.
- Measures air velocity, volume flow, and temperature
- Measures in-duct air flow, and automatically calculates volume flow (simply enter the duct dimensions)
- Small diameter (<0.5”) and 15” telescopic shaft length is ideal for in-duct flow averaging and timed traverse
- Perform air duct leakage tests
