Testo 405 Digital Anemometer

Technical specifications:

The Testo 405 Digital Anemometer is characterized by having a permanently mounted telescope, extendable up to 300 mm, which allows the measurement of air speed, volume flow and temperature in any ventilation duct, in a very simple way and with a high level of precision.

In addition, its one-line backlit LCD digital display can be rotated in different positions, making it easier to read the measured values from different angles.

On the other hand, because its measurement range is between 0 m / s and 10 m / s, it is ideal for measuring air velocity in low speed ducts.


Among other features of the Testo 405 Digital Anemometer, the following can be mentioned:

- The length of the probe tube is 300 mm, its diameter being 16 mm,

- The diameter of the probe tube tip is 12 mm,

- It has a temperature measurement range that goes from -20 ° C to 50 ° C, with an accuracy level of ± 0.5 ºC,

- It has a speed measurement range that goes from 0 m / s to 10 m / s, with a precision level of up to ± 0.1 m / s + 5% of the measured value, when the speed is between 0 m / s and 2 m / s,

- It has a flow measurement range that goes from 0 m³ / h to 99,990 m³ / h,

- It has dimensions of 490 mm long x 37 mm wide x 36 mm high,

- Its weight is 315 grams,

- The head with the screen can be rotated to three positions, in order to facilitate the visualization of the measurements made,

- It works with 3 AAA batteries, which give it an autonomy of up to 20 hours of operation,

- With the purchase of the Testo 405 Digital Anemometer, a conduit holder, a clip to hang it from the belt and 3 AAA batteries are also included.
