- For measuring volume flow, air velocity and temperature
- Simple configuration of the dimension and geometry of the duct cross-section for determining the volume flow
- Convenient for working in ventilation ducts thanks to its telescopic tube, which can be extended up to 400 mm
- Really convenient to operate thanks to the testo Smart App (e.g. easy viewing of readings, measurement data trend, log function)
With the testo 405i hot wire anemometer, you can measure air velocities, temperatures and volume flows. Via Bluetooth, the readings are transmitted wirelessly straight to the testo Smart App on your smartphone or tablet. You can view the values conveniently and use numerous intelligent features.
