Mobile Smart Probe

This month we feature the Testo Smart Probe App which turns your mobile phone or tablet into a remote control and measurement device. The app works with the following Testo measurement instruments:

Pictured here are the four major screens in the Testo Smart Probe App.

  • 405i
  • 410i
  • 605i
  • 510i
  • 115i
  • 549i
  • 805i
  • 905i
  • testo 552
  • testo 770-3.

It works on both iOS and android mobile devices.

The app uses Bluetooth technology to share air conditioning and refrigeration measurement data, Airflow (register and grille), infrared temperature and mold indicators, and more. The app can create and send PDF reports (including photos of the measurement location) and can handle up to six probes at the same time.

This FREE app is available in both the Google and Apple Stores.
