Product Profile of Water Vapour Permeability Tester
PBI-Dansensor offers Water Vapour Permeability Tester. PBI-Dansensor manufactures gas analysers, gas mixers, gas flow control, etc. The Water Vapour Permeability Tester, L80-5000 helps to measure both low and high permeability materials using special sample reduction cards that decrease the surface area of the sample. This reduction of the surface prevents the system from getting saturated, and therefore it becomes possible to dry down the upper chamber of the tester and obtain a permeability measurement. The L80-5000 Water Vapour Permeability Tester provides an excellent correlation to most gravimetric measurement methods. In addition, the distance between the humidity sensor and the film in this tester are constant and it provides consistent and accurate results from instrument to instrument.
Key Features of Water Vapour Permeability Tester
- Easy and fast preparation: Preparation of a sample is accomplished in minutes. No grease or glue is required for a tight seal around the sample in the chamber.
- High reproducibility: Ring tests performed by a series of users have proven that the standard deviation of the Lyssy instruments is lower than +/-5%, and the reproducibility tolerance is less than 1, 5%.
- No influence of flow: It does not have varying air flow in the climatic room and with a static measurement method; this Permeability Tester does not have this problem.
- The broad range of testing capacity: It can be used to measure both high and low permeability materials.
- Time saving: A measuring time of 8 to 15 minutes for a high permeability film gives the user the possibility to control the quality of the film with minimal wastes, since the operator is then able to adjust the settings of the production machine to optimize the quality of the film.
- Measurement done under realistic conditions: The Lyssy Water Vapour Permeability Tester measurement method provides a realistic WVTR measurement of the material.
