Product Description
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, at draughty windows for example, are quickly located and accurately measured using the anemometer.
Integrated sensor protection: when you are not using the testo 405 thermal anemometer, the rotating protective cap protects the flow sensor from mechanical stress.
