Product Description

Application:
WVTR-398B is based on the humidity sensor detection method and available for the water vapor permeability test of heat exchange membranes, nonwoven fabrics and flexible barrier materials.

Features:

features	Weighing method
	Dual weighing modules, patent technology
	18 specimens, continuously test
	One-button test, test automatically in whole process
	Multiple test modes optional
	Temperature and humidity auto control
	Data curves display
	Computer control
	Environment temperature and humidity sensor inside
	Unit based on embedded system,24bit Δ-Σ AD
	Traceable reference film calibration
	Supports DSM system (DSM, lab data management system)

Principles：
The specimen is clamped between the upper and lower chamber, the upper chamber is high humidity side, and the other side of specimen, lower chamber is purged by a stream of dry gas, due to the effect of water concentration gradient at two sides of the specimen, water molecules will permeate through the specimen into the dry gas side, penetrated water molecules will be carried to the relative humidity sensor which generates the proportional signal, so water vapor transmission rate will be obtained by calculating the sensor signal.
