About This Product
Leather used for shoes, bags and garments should let moisture pass through it, and the water vapour permeability test measures how much it lets through. A leather specimen is fixed over the mouth of each bottle, the bottles are rotated for a set time while the fan moves air across the openings, and the change in mass is used to work out the permeability. The timer sets the length of the run. School Lab Equipment India can export the Water Vapour Permeability Tester to education buyers in Iceland, Libya, Kyrgyzstan, Panama, Republic of the Congo and Zimbabwe.
