Product Introduction / Product introduction

Detection principle

At a certain temperature, a specific humidity difference is formed on both sides of the sample, and the water vapor enters the dry side through the sample in the permeable cup. By measuring the change of the weight of the permeable cup with time, the water vapor transmittance and other parameters of the sample are obtained.


Technical description of WTR-06 water vapor transmittance tester
