The Moisture Transmission Testing for Moisture Proof Package

An article by admin    No Comments

Moisture proof package is for protection against moisture during logistics. Moisture proof package is widely used in machinery, electronics, foodstuff, medicine and daily care, etc. It is a most commonly used protection against moisture during logistics. Moisture proof package avoids rusts and deterioration of the packed contents effectively. Labthink, as the excellent provider of testing instruments and testing services, integrates moisture proof methods with relevant methods for introduction.

The moisture proof packages are tested according to cup method as regulated in the standards. Cup method is another name for weighing method when testing moisture. Its principle is to test the weight differences of the cup within a unit time so as to get the parameters such as moisture transmission quantity. Hereinafter, we take Labthink TSY-T series of testers as example. This series has four testers, all of which are of weighing method.

The traditional testing method is to utilize cup, constant temperature chamber and scale to measure manually. However, owing to the human interferences, there would be a great influence on testing results, such as long testing duration and low accuracy. Labthink TSY-T series of moisture transmission testers are the global innovative fully automotive testing mode, complying with testing requirements as well as standards. The only thing the operator needs to do is to place the prepared specimen into the cup and start the tester. Then, the tester operates, judges, ends and prints the testing results automatically. The whole process is intellectual with no human interferences and thus, brings forward accurate and reliable testing results.

Besides, in actual application, the packaging material must undergo procedures such as forming, inserting and heat seal, etc; and uneven thickness and inferior sealing sometimes occur. This requires testing for packaging materials as well as the whole moisture proof package. Labthink PERME W3/330 Moisture Transmission Testing System successfully meets the double testing need. This testing system is of master-satellite mode, a master base can connect 9 satellite testers so as to realize 30 kinds of materials tested at the same time.
