Sniffing leak detector according to the reference measurement principle

摘要

A sniffing leak detector comprises a handle with a sniffing tip. Located at the sniffing tip is a measurement gas suction opening and a reference gas suction opening. The reference gas suction opening is intended for suctioning ambient gas. The reference gas suction opening is aligned substantially the same as the measurement gas suction opening such that both suction openings are sensitive in the same direction.
