The Testo 410i is a compact wireless vane anemometer designed for measuring air flow, volume flow and temperature. The pocket-sized instrument provides fast accurate readings at ventilation grilles, ducts and air outlets. Constructed from high-quality impact resistant materials the tough mini anemometer is the ideal instrument for HVAC technicians and service engineers.

The small, perfectly formed anemometer uses a precision 40 mm rotating vane sensor and built-in NTC thermistor sensor to deliver readings with extreme accuracy. The 410i anemometer records wind speed from 0.4 to 30 m/s while the NTC sensor range goes from -20 to +60 °C.

The Testo 410i handheld anemometer connects via Bluetooth to Android, iOS smartphones and tablets. It can display real-time air temperature, airflow velocity and volume flow measurements on to the user's screen. The Testo Smart Probes App enables you to configure, view and calculate all from your mobile device. Additionally, all data and information can be saved into Excel and PDF formats for logging and sharing. Up to six separate devices can link to the App at any one time allowing remote system set up and monitoring.

The Testo Smart Probes App is available to download free from the App Store or Google Play and is compatible with all of the instruments from the Testo Smart Probes range. The app can display real-time measurements and results on the screen. Anything up to six Smart Probes can work in tandem and the information (including pictures) can be saved in Excel or as a pdf document.
