Digital Display Oxygen Index Tester DH-OI-02

Number:

LT-01 Leak Tester can be used for soft packaging sealing testing in food, pharmaceutical, daily chemical, electronics and other industry. By testing, the sealing process and performance can be ef- fectively compared and evaluated, providing scientific basis for determining relevant technical specifi- cations. The LT-01 Leak Tester can be also used for sealing performance tests after falling and com- pressing testing.
