If, in your capacity as an HVAC engineer, you carry out fast check measurements in ventilation ducts or in rooms, then our testo 405 thermal anemometer is a must-have. This versatile testo thermal anemometer features a permanently mounted telescope and enables you to measure air flow, volumetric flow, and air temperature. The measuring range for flow is between 0 to 10 m/s, while volumetric flows are calculated up to 99,990 $m^3/h$.
The extendible telescope (up to 300 mm) makes the testo 405 particularly suitable for flow measurements in ventilation ducts. The illuminated display can be swivelled into various positions, ensuring that the readings can be read off comfortably. The included duct bracket offers key practical advantages, allowing you to optimally position the telescope in the ventilation duct to obtain precise measurement results.
Since the testo 405 thermal anemometer measures particularly accurately in the range between 0 and 2 m/s, you can also use it to measure the air velocity in rooms. Low air velocities, such as those found at draughty windows, are quickly located and accurately measured using this compact testo thermal anemometer. It is the ideal tool for ensuring indoor comfort and system efficiency.
Integrated sensor protection is a key feature of the testo 405. When you are not using the device, a rotating protective cap protects the thermal flow sensor from mechanical stress and dust. This ensures that your testo 405 thermal anemometer remains accurate and reliable for long-term use in the field.

Frequently Asked Questions
The testo 405 is primarily used by HVAC engineers for quick and accurate measurements of air flow velocity, volumetric flow, and air temperature. It is specifically designed for spot-check measurements in ventilation ducts and for monitoring air velocity in rooms to identify drafts.
This testo thermal anemometer features a permanently mounted, extendible telescope that reaches up to 300 mm (approx. 12 inches). This makes it much easier to perform flow measurements deep inside ventilation ducts.
Yes! One of the standout features of the testo 405 thermal anemometer is its high accuracy in the range of 0 to 2 m/s. This sensitivity makes it perfect for detecting low-speed drafts near windows, doors, or ventilation outlets
Absolutely. The testo 405 comes with a swivel-mounted, illuminated display. You can rotate the screen into various positions, ensuring you can comfortably read the measurement data even when the telescope is inserted into a difficult-to-reach duct.
The testo 405 thermal anemometer includes an integrated rotating protective cap. When you are finished with your measurements, simply twist the cap to shield the thermal flow sensor from dust, dirt, and mechanical stress.
When you order the testo 405, you receive the thermal anemometer with the extendible telescope, a duct bracket for stable positioning, a multi-function clip, and the necessary batteries so you can start measuring immediately.
