The principle of the Vapor Permeameter is the same as that of the Diffusion Permeameter except that instead of a gas, any noncorrosive vapor is used and the flow rate of the vapor is determined.
- The sample chamber is maintained at a constant temperature for yielding reliable and reproducible data.
- Fully automated
- Very little operator involvement
- Test time: Can be as little as a few minutes
- Robust. Minimal maintenance
- Measurable flow rate. As low as 10-4 cm3/s
