AUTO W46/1 Infrared Method Water Vapour Permeability Analyser
Product Introduction
AUTO W46/1 Infrared Method Water Vapour Transmission Rate Tester is based on the testing principle of the infrared method, designed with reference to GB/T 26253, ASTM F1249 and other standards. It tests the water vapour transmission rate of samples under set temperature and humidity conditions (quantity), suitable for water vapour transmission rate performance testing of films, sheets, paper, packages and various materials in the fields of food, medicine, medical equipment, daily chemicals, photovoltaic electronics, etc.
It is an ideal configuration instrument for off-line or on-line testing of the barrier properties of packaging materials for production units in the packaging industry.
Test Principle
The AUTO W46/1 adopts the principle of infrared method. Fix the pre-treated sample in the middle of the test chamber, divide the test chamber into a high-humidity side and a low-humidity side. The humidified nitrogen flows on one side of the film, and the dry nitrogen (carrier gas) flows at a fixed flow rate on the other side. In the presence of a humidity gradient, water vapour will permeate from the high-humidity side to the low-humidity side, and the water vapour that passes through the sample is carried to the infrared sensor by the flowing dry nitrogen, and the water vapour transmission rate (and other parameters) of the sample is obtained by the electrical signal output by the sensor.
