Packaging Materials Water Vapor Transmission Rate Testing Machine
Water vapor transmission rate is an important data of packaging materials and finished packages. It directly affects how well packages protect content.
W3/230 Water Vapor Transmission Rate Testing Machine is designed according to the principle of water vapor’s particular spectrum absorption to infrared. The system generates a humidity difference between the two sides of specimen, which forces the water vapor diffuses from the high to the low and water vapor from the low side enters into the infrared sensor. Through detection of infrared energy loss when passing the water vapor space, water vapor density will be measured by the infrared sensor, on which basis the transmission rate of specimen will be calculated.

W3/230 water vapor transmission rate testing Machine can test three different specimens with indepent test results at the same time. It also equipped with precise temperature and humidity control device to meet various test requirements.
W3/230 water vapor transmission rate testing machine can be easily connected with 9 satelites system.
