Description
Testo 405-V1 Pocket-Sized Thermal Anemometer (metric only)
Flow velocity measuring instrument with temperature measurement
Use the testo 405 thermal anemometer to measure air velocity, volumetric flow, and air temperature. It is suitable for carrying out quick check measurements in ventilation ducts, and for measuring the air velocity in rooms, such as at drafty windows. If, in your capacity as an HVAC engineer, you carry out fast check measurements in ventilation ducts or in rooms, then the testo 405 thermal anemometer is a must-have. The anemometer features a permanently mounted telescope and enables you to measure air flow, volumetric flow, and air temperature. The measuring range for flow is from 0 to 10 m/s, and volumetric flows are calculated up to 99,990 m3/h. The extendible telescope (up to 300 mm) makes the thermal anemometer particularly suitable for flow measurements in ventilation ducts. The illuminated display can be swivelled into various positions, ensuring that the readings can be read comfortably. The duct bracket (included in the delivery) offers key practical advantages. You can use this to optimally position the telescope in the ventilation duct and 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, 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.
