Automatic power failure saving function to avoid test interruption

Automatic record of the whole testing process, result judgement and results saving function

Efficient testing, low nitrogen consumption and short test time

System self-detection function to avoid continuing testing in the state of failure

Real-time monitoring of gas flow, automatic alarm when gas running low

Rapid access to the temperature and humidity calibration port, convenient to quick calibration

Test Principle

The test specimen is mounted in the diffusion cell, which is 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.
