AN APPARATUS FOR MEASURING THE DEGREE OF VACUUM IN THE PRODUCTS

摘要

An apparatus for measuring the degree of vacuum inside products is provided to improve measure measurement accuracy at low cost by adding several simple elements to a conventional measuring apparatus. An apparatus for measuring the degree of vacuum inside a product includes a nipple(90), a sub hose(100), and a centering(110). The nipple is connected to an inlet of a vacuum sensor(60) and is a coupling unit connecting the vacuum sensor and the sub hose with airtight. The sub hose is inserted in a vacuum hose(30) and extended near a socket coupler(40). The socket coupler is coupled to a plug coupler(50). The plug coupler is a coolant pipe(55) for measuring the degree of vacuum accurately at most. The centering is coupled to an end of the sub hose for locating the sub hose at an inside center of the vacuum hose and shields foreign substance from the end of the sub hose.
