Infrared Method Water Vapor Transmission Rate Tester W401 2.0 Introduction AUTO W401 2.0 Water vapor transmission rate tester is designed and manufactured according to ASTM F1249 and GB/T 26253 standards, based on the testing principle of infrared method, it provides wide range and high efficiency water vapor transmission rate test for high, medium and low barrier materials is suitable for water vapor transmission performance testing of films, sheets, paper, packaging and other related materials in the fields of food, medicine, medical equipment, daily chemistry, 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 AUTO W401 2.0 water vapor transmission rate tester 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 vapor will permeate from the high-humidity side to the low-humidity side, and the water vapor that passes through the sample is carried to the infrared sensor by the flowing dry nitrogen, and the water vapor transmission rate (and other parameters) of the sample is obtained by the electrical signal output by the sensor.
