Thermo-anemometer (air flow meter-thermometer) with a telescopic air flow and temperature measuring probe connected to the cable, measures both air flow speed and temperature, as well as calculates the air flow volume.

- Simple, fast and accurate measurement and calculation of flow volume in ventilation pipes.
- Increased measurement flexibility thanks to the telescopic probe attached to the cable (max. length 820 mm).
- The meter can be connected to a smart device using the Testo Smart App. The application has a menu of the measuring device, it is possible to see the history of measurements, graphs of measurements, create reports and use the smart device as a second display of the measuring device.
- Calculation of average values at a given time and point.
