Thermal Anemometer-Testo 405 -

Description

If you perform quick check measurements in ventilation ducts or rooms as an HVAC engineer, the testo 405 thermal anemometer is a must-have. You may measure air flow, volumetric flow, and air temperature with the thermal anemometer, which has a permanently mounted telescope. The flow measurement range is 0 to 10 m/s, and volumetric flows can be computed up to 99,990 m3/h.

The thermal anemometer’s extendible telescope (up to 300 mm) makes it ideal for flow measurements in ventilation ducts. The LED display can be swivelled into a variety of settings, making it easy to view the information. The duct bracket (included in the delivery) provides significant benefits. This can be used to orient the telescope in the best possible way.

You may also use the thermal anemometer testo 405 to measure air velocity in rooms to examine indoor air quality because it measures particularly accurately in the range of 0 to 2 m/s. The thermal anemometer can quickly find and precisely measure low air velocities, such as those seen in draughty windows.

Sensor protection: the rotating protective cap protects the flow sensor from mechanical stress when the testo 405 thermal anemometer is not in use.

Applications

Measurement in ventilation ducts

Observance of air flows in the ventilation duct is of utmost importance for the function of the ventilation and air conditioning system. If the air flows are smaller than intended, the removal of room loads (heating, cooling and substance loads) may not be ensured in certain circumstances. Therefore, the most accurate recording of air flows as possible is particularly important.

Our thermal anemometer testo 405 allows particularly cost-effective measurement of low air velocities. It enables the accurate and parallel measurement of air flow, volumetric flow and temperature. The extendible telescope allows measurement at a depth of up to 300 mm.

The display can be swivelled into various positions, enabling optimum measurement readout.
