Permeability Meter Weight Method Cup Method Building Material Water Vapor

Prodects Details

Application:

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. Building Material Water Vapor Permeability Meter Weight Method Cup Method.


Building Material Water Vapor Permeability Meter Weight Method Cup Method Features:

— Relative humidity sensor detection method

— Embedded system, remote maintenance and update

— One specimens test

— Highly automatic test in entire process

— Highly accurate water bath temperature control technology

— Highly accurate RH detection sensor inside

— Swagelok stainless steel pipes with long service life

— Digital flow adjustment

— Chamber with temperature sensor monitoring (DALLAS)

— Data curves display

— Computer control

— Overload protection

— Traceable reference film calibration

— 5 grades user managements, GAMP5 regulations

— System log file

— 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.
