- Wide measurement range:
- Bendtsen, ml/min 5 – 400
- Coresta, ml/min 1 – 100
- Gurley, s 30 – 2000
- Others on request
- Fast measurement; Less than 10 sec even fore very low porous materials
- Very easy to measure CD profiles
Air permeability measured typically as Gurley unit is one of the key characteristics of a battery separator film. The separator with uniform permeability is essential for the long cycle life of a battery. Variations in permeability will result in uneven current density distribution, which may be a risk for the whole battery. ACA Permi Lab can measure with repeatability and fast the gurley values of the BSF-film either from single point or CD profile
Breathable films are used extensively in diapers and food packaging. For the end-use the quality of the film needs to be constant and breathability variations minized. ACA Permi Lab can measure with repeatability and fast the breathability values of the film either from single point or CD profile
