The robust thermo-anemometer for reliable leakage tracking on the building site!

Use the handy SwemaAir 40 to locate leakage in the building envelope at depressurisation during the BlowerDoor test. Sweep all connections, joints, and penetrations with the telescopic probe of the SwemaAir 40. Thanks to its increased sampling rate of 4/sec to be better able to track leakage, the temperature and air speed meter SwemaAir 40 will immediately show you even the slightest air flows. The shortened tip of the telescopic probe even in the corners of a room enables you to locate leaks easily. The display shows the result of the measurement in m/sec. There are two measuring ranges available for the exact measurement of the airflow.
The straight probe can be extended up to 66 cm. It can be attached to the SwemaAir 40 as desired, so that the device can be operated with one hand only. The sturdy casing of anodised aluminium with rubber-coated front ends is particularly impact-resistant and is gentle on sensitive materials.

A top-grade thermal anemometer: The AirflowTA7

The thermo-anemometer TA7 has been developed specifically for locating leakage and during the BlowerDoor tests of the building envelope reliably measures even the slightest airflows. At negative pressure, these airflows infiltrate the interior of the building through connections, penetrations and joints that are not airtight. The offsetable telescope probe with its sensitive sensor allows you to carry out measurements even at hard-to-reach building components. During use it can be extended to a total length of 105cm. On the display of the TA7, airflows are visualised analogously by an LCD-bar. This makes it easier to observe the trends and ranges of the fluctuations. In addition, the measuring result is displayed in easily readable digital numbers in m/sec. The TA 7 offers a choice of three measuring ranges for the reliable and exact acquisition of the air velocities. The equipment comes in a robust transport and storage case.
