The TE – measuring head is based on the established Venturi nozzle principle. This probe's TE head should be oriented upwards. The end piece of this probe is compatible with the SUN and UN adapters. While using the UN adapter on this probe, there is a visible gap between probe and adapter. We offer a spacer to bridge the gap. Warning: prior to inserting, the end piece should be lightly lubricated.
Note: "Illustrations are similar. Almost all products are made by hand. Minor deviations are not grounds for complaint."
