Detailed Description

Water Vapour Film Permeability Measurement

Water Vapour Film Permeability Measurement is manufactured based on the gravimetric method, and is applicable to test the water vapor transmission rate of plastic films, composite films, sheets and other materials used in packaging, medical and constructive industry.

Water Vapour Film Permeability Measurement Features

Ø Standard periodic weighing method and auto-zeroing function guarantee the accuracy and uniformity of the testing data.

Ø Touch interface is more convenient to operate.

Ø The test data is reliable due to the automatic process and the weighing system controlled by the gas cylinder.

Ø Innovative circulating dehumidification system with built-in vacuum pump can effectively prevent the formation of humidity gradient and ensure the accuracy.

Ø High-precise and automatic control system of temperature can be used under different conditions.

Ø The data can be stored and outputted in multi-format (including report in excel and cloud sharing).

Ø The rapid calibration mode with standard weight-counter is provided.

Ø GMP management of user's three-level authority complies with international standard.

Ø The instrument processes statistical analysis of single and group data.

Ø Equipped with ISP control online and upgrade function.

Ø Specialized communicating software can display in real-time, analyze and store data.

Water Vapour Film Permeability Measurement Principle

Under a certain  temperature, the constant difference of humidity is generated between two sides of the test specimen. The water vapor permeates through the specimen and gets into the dry side. By measuring the weighing changes of the test dish in different time, water vapor transmission rate and other parameters can be obtained.

Water Vapour Film Permeability Measurement Standards

ISO 2528, ASTM E96, ASTM D1653, TAPPI T464, DIN 53122-1, JIS Z0208, GB/T 1037, GB/T 16928, YBB 00092003.
