IFA-300 Constant Temperature Anemometer DE

Artikelnr: 183151


The IFA 300 Constant Temperature Anemometer (CTA) is a state-of-the-art research anemometer capable of meeting the most demanding measurement requirements. Whether your application involves measurement of high speed flows (gas or liquid), measurement of very low turbulence intensities, or the use of a high-power bridge, the IFA 300 can provide the solution. It represents the depth of design capability and an understanding of the dynamics of constant temperature anemometry, which TSI has developed over the past 50 years of building exceptional anemometry products. 

The IFA-300 anemometer can be used with all thermal anemometer probes manufactured by TSI, in order to perform velocity measurements in gas or liquid. The unit is designed to house up to eight CTA channels in one cabinet, with a total of 16 CTA with two cabinets. These arrangements allow multiple thermal anemometer probes to be used for measurements of multiple components (1D, 2D or 3D), and in multiple locations in the flow field.
