The measuring head has two precisely defined slots for the very clean PD acceptance – older versions still have holes. This design shows very good values in the wind tunnel when oriented upwards. Due to the design, the head can be replaced very easily. With this end piece, the probe fits into the built-in adapters type ST1 and SUN, as long as the interchangeable insert wTEK is used in them!
Note: "Illustrations are similar. Almost all products are made by hand. Minor deviations are not grounds for complaint."
