○ Overview:
GTI Jinko Fully Sealed Airtightness TesterThe AL-900S series is a differential pressure leak detector developed by our company for fully sealed and waterproof products. The instrument adopts a high-sensitivity differential pressure sensor with high testing accuracy; Adopting a large-diameter pneumatic control valve, it has the advantages of fast inflation speed, good sealing, no heating, and long service life. The design of a brand new gas path structure, with one-step testing for large and small leaks, improves efficiency by 100% compared to traditional principle instruments. Suitable for online product testing, and also an ideal instrument for equipment matching.
○ Features:
☆ 5.6 "full touch color LCD display screen, clear operation interface
☆ Integrated high-precision, small volume differential pressure sensor
☆ Equipped with self-developed intelligent testing valve island components, it has a long lifespan and good stability
☆ Multiple communication interfaces such as RS232/485 and Ethernet ports (supporting Modbus)
☆ Configure scanning interface to achieve data management and quality traceability
☆ Leakage units available in Pa, mL/min, Pa/s, and sccm
☆ 100000 sets of data storage, can be viewed and exported via USB
☆ Multi level user management permissions (up to 10 sets of usernames can be added)
