The Testo 405- V1 Meteric Thermal-Anemometer.

Testo's velocity STICK has a rapid response sensor for detecting the most minute changes in air velocity such as windows, door and heat exchanger leaks. This mini-anemometer reads air velocity (m/s only) and temperature (°C only) and calculates volume flow in cubic meters per hour.
