Users can read the measurements using the testo Smart Probes App installed on their smart device. It is easy to configure volume flow measurements and to reliably run timed multipoint averaging traverses. It is especially useful for balancing multi-outlet ventilation systems by using several instruments. The testo 410i works on smart devices with either Android or Apple operating systems.

The testo 410i Smart Probe is a compact wireless vane anemometer for measuring air velocity, temperature, and deriving volume flow. It can be used at air outlets, and for monitoring the air flow of ventilation systems.

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, as well as air flow at registers, and automatically calculates volume flow (simply enter the duct dimensions)
  • No air density correction required, due to its design
  • Measure volume flow at several outlets simultaneously (using mutiple Smart Probes), to adjust system balance
  • Timed/multipoint averaging to get accurate air flow profiles
