Product Description

Paper and Paper Board Water Vapor Transmission Rate Instrument is based on the cup method, and is professionally applicable to the water vapor transmission rate test of plastic films, composite films, sheets and other materials used in medical and construction industry. By testing the water vapor transmission rate, the technical index of the materials could be controlled to meet the requirements for production.

Application:

Paper and Paper Board Water Vapor Transmission Rate Instrument is applicable to the determination of water vapor transmission rate of:

Basic Applications	Films Including plastic films, plastic composite films, paper-plastic composite films, geomembranes, coextruded films, aluminized films, aluminum foils, aluminum foil composite films and many other film materials
	Sheeting Including engineering plastics, rubber, waterproof building materials and thermal insulation materials, e.g. PP, PVC, PVDC and nylon
	Paper and Paper Board Including paper and paper board
	Textiles and Nonwovens Including textiles and non-woven materials

Features:

Standard periodically weighing method and auto zero before each weighing guarantee the accuracy and uniformity of the testing data
Three specimens could be tested simultaneously and the test dishes are lifted and lowered by the gas cylinder which ensures the reliability of the test
Standard air velocity to prevent the humidity difference spread which ensures the accuracy of the test
Wide range and high-precision of automatic temperature and humidity control to support various combinations of non-standard test conditions
Universal RS232 communication port is convenient to the data export and transmission
