The cross-sections of the air ducts to be measured – whether round or square – can be entered into the device in a differentiated way.

Being a dynamic pressure anemometer with Pitot tube, the TA400 also allows you to determine the differential and dynamic pressure. The Pitot tube fulfils all requirements, particularly for high flow rates and dusty air, since it has virtually no mechanical or dirt-sensitive sensors – hence, it is perfectly suited even for application in extremely rough surroundings.

In addition to air current control in ventilation ducts and other typical measuring tasks in the area of air conditioning and ventilation, the TA400 also covers additional fields of application thanks to its capability of measuring pressure. These fields include filter status measurements in air conditioning systems and differential pressure measurements in gas-fired boilers.

Moreover, this differential pressure measuring device is also optimally suited for pressure control in sealed-off zones with high or low pressure atmospheres, for example during restoration work in areas contaminated by mould.

Since the TA400 additionally comes with an internal memory administration, you are able to store the measured pressure, flow rate and volumetric flow data in the TA400 anytime during a measurement separately in up to 99 data sets, or call up or delete stored values.
