Product Details
Application:
WVTR 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:
| tures | Weighing method |
| Dual weighing modules, own technology | |
| *8 specimens, continuously test | |
| One- 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,*4bit 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.
