Welcome: U-THERM INTERNATIONAL (H.K.) LIMITED
Product Description:
Fit for sealing tests of packaging bags, bottles, tubes, cans, boxes in food, pharmaceutical, medical device, cosmetic, automotive, electronic components, stationery industry, etc. Also could do the sealing performance testing on the specimens after falling and withstand voltage test.
Product Features:
1. Steadily, rapidly form vacuum test environment;
2. Higher vacuum degree, ensure that it is up to above -90KPa;
3. Microcomputer integrated circuit control, procedural, automation test process;
4. Using high-quality system components, stable performance;
Test principle:
Throughvacuumizing in the vacuum chamber, make the sample immersed in water producing internal and external differential pressure, observe the gas escaping condition in the sample, in order to determine the sealing properties of the specimen; through vacuumizing the vacuum chamber, the sample generate external pressure difference, observe sample expansion and release form after vacuum sample recovery, in order to determine the sealing properties of the sample.
Structure and Composition:
Transparent vacuum chamber, microcomputer control circuit board, vacuum generator system.
Standards Compliant:
ASTM D3078
