INTRODUCTION TESTO 405 – POCKET-SIZED THERMAL ANEMOMETER
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 drafty 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.
Features Testo 405 – Pocket-sized thermal anemometer
- Volume flow calculation of up to 99,990 m3/h
- Easily read data at any angle with rotating display
- Telescopic handle up to 300 mm
- Ideal for measurements in ducts
- Measure air velocity, volumetric flow, and air temperature
- Suitable for carrying out quick check measurements in ventilation ducts, and for measuring the air velocity in rooms, such as at drafty windows.
