Product Performance

By filling compressed air of specified pressure into the measured object (product), this instrument detects whether there is leakage according to the change of its internal pressure. Firstly, the leak detector fills the measured object with the regulated gas, and then stops the inflation to maintain pressure. During the pressure maintaining process, it senses the pressure drop caused by leakage, that is, direct pressure leakage rate, through a high sensitivity pressure sensor.
