Electrolytic detection method water vapor permeability tester is applicable for water vapor permeability test of various packaging materials (such as plastic films, laminated films, etc.) and many kinds of barrier materials in pharmaceutical industry. Users can control and adjust the technical index by testing the water vapor transmission rate. In product application, it can satisfy different necessaries of users.

1. Characteristics

.Electrolytic method, computer control, highly accuracy and test automatically.

.Highly sensitive, accurate and reliable test data.

.Adjustable test temperature and humidity, easy to fulfill different test conditions.

.System generates test environment independently, no requirements about lab conditions.

2. Principle

Place the specimen between dry and humid chambers, saturated water vapor will transmit through specimen from the upper chamber to the lower chamber and then be carried to the sensor, which generates electrical signal at the same time. Determine the mass of water vapor transmission and water vapor transmission rate by analyzing and calculating the sensor's electrical signal.

3. Structure

It is made up with mainframe and outer circulate controller. Mainframe implements specimen test and outer circulate controller supplies test conditions.
