The test specimen is mounted in the diffusion cell, which is subsequently divided into a dry chamber and a controlled-humidity chamber. The dry side of the specimen is swept by a flow of dry nitrogen, and the water vapor permeating through the specimen from the controlled-humidity chamber is carried by dry nitrogen to the infrared sensor where proportion electrical signals will be generated. The water vapor transmission rate is obtained by analyzing and calculating the electrical signals. For package specimen, the dry nitrogen flow inside the specimen while the outside of specimen is in high humidity environment.
This test instrument conforms to the following standards:
ISO 15106-2, ASTM F1249, GB/T 26253-2010, TAPPI T557, JIS K7129, YBB 00092003-2015

This instrument, based on infrared sensor method, is equipped with advanced technology and components so it can test the water vapor transmission rate with high resolution and sensitivity. With innovative design of structure, the instrument facilitates with more test modes and functions, which can meet the testing requirements for materials with high, medium and low barrier properties.
Based on infrared sensor method, the instrument adopts Labthink’s second generation patent design of three diffusion cells integrated in one instrument, which improves the test resolution, repeatability and performance in temperature and humidity control.
The instrument is embedded with Labthink’s latest operating software, which is featured with user-friendly interface, intelligent data processing, strict user management and secure data storage. It also supports Labthink exclusive DataShieldTM Note4 (Optional) which provides the users with safe and reliable management of test data and test reports.
Note 1: The parameters in the table are measured by professional operator in Labthink laboratory according to relative requirements for laboratory standard conditions.
Note 2: The described product features, test standards and configurations should be in line with Table 1: Test Parameters.
Note 3: DataShieldTM provides safe and reliable data application support. Multiple Labthink instruments can share one single DataShieldTM system which can be purchase as required.
