Anvendelse
Test af pakkeforseglingers integritet er med til at sikre, at emballagen yder den nødvendige produktbeskyttelse. Bæredygtige emballagealternativer, billigere emballage og variationer i produktionslinjens forseglingsparametre vurderes ofte med test af forseglingsintegritet. Det er afgørende for produktkvaliteten og -sikkerheden, at pakningernes pålidelighed opretholdes.
Testbeskrivelse
A sample is placed into the chamber filled with water. Then the chamber is covered with a lid and they are well sealed. Manually open the gas switch so compressed air flows through the venturi tube to provide a vacuum inlet, which is connected to chamber. A gas regulator can adjust the vacuum degree so sample is in a vacuum environment. The pressure difference between inside and outside of sample will cause the headspace gas to escape if there is a leak. The leak is shown by a stream of bubbles coming out from the leak area.
Tekniske funktioner
LT-01 leak tester is the manual model developed. It’s an economic, strong and long durable model.
- For at opnå et stabilt vakuum og i betragtning af, at det er lettere at få fat i trykluft på brugerens anlæg, bruger vi Venturi-rør til et højt vakuumniveau på op til -90KPa.
- Strong and clear chamber provided, same type as equipped to our automatic models; Different sizes and shapes could be customized
- It could be modified to work with vacuum pump, to achieve higher vacuum (for ASTM D4991)
- No calibration needed
- No electricity needed
