The X550A high-precision differential pressure leak detector is microcomputer controlled and combines advanced data acquisition and analysis technology with precision sensors. The test process is fully automatic and easy to operate. The instrument provides multiple communication interfaces for connecting PLCs, PCs and other host computers. A 5-inch colour touch screen makes parameter setting and test-record review easy. The instrument is CE certified, and a CNAS certificate from the Guangzhou Institute of Measurement is available as an option.
The high-precision leak detector is CE certified. Certificate no.: M.2024.206.C99088; verification website:https://www.udem.com.tr/
