This multiprobe is a combination of a gun tube and a venturi nozzle, making it more robust and heavier than the KFK version. The PD decrease should be oriented upwards. Attention, always push the probe in as far as it will go and lightly grease the end piece to a length of about 8cm before inserting it.
Note: "Illustrations are similar. Almost all products are made by hand. Minor deviations are not grounds for complaint."
