The TR-WVTR-9002 is designed based on the electrolytic sensor method and is ideal for testing the water vapor permeability of flexible films, sheets, and packaging materials. It can test up to three samples simultaneously while providing an average result for improved accuracy. 1. Utilizes electrolytic sensor technology

Film:
The sample is clamped between two chambers. The upper chamber is purged with high-humidity nitrogen, while the lower chamber is flushed with dry nitrogen. Due to the water concentration gradient across the specimen, water molecules will pass through it into the dry side, where they are carried to an electrolytic sensor that generates a proportional signal. This signal is used to calculate the water vapor transmission rate.
Package:
The package is mounted on the lower chamber. The outside of the package is maintained at a specific relative humidity, while the inside is purged with dry nitrogen. Water vapor permeates through the package walls and is detected by the same electrolytic sensor, allowing for the calculation of the transmission rate.
