Project Description

Water vapour permeability test chamber

Water Vapour Permeability Test Chamber is used for determining the water vapour permeability (WVP) of leather or fabrics in an artificial environment in accordance with prescribed requirements.

Compared with the AT-L9014 WVP tester, this device features an extra climate chamber coming with a temperature and humidity controller, which is capable of providing a specific temperature and humidity atmosphere ( 23 ± 2℃, 50 ± 5% R.H. specified by ISO 20344) for the test.

Test Standards

GB/T 20991, SATRA TM172, EN / ISO 20344, ISO 20345, ISO 20347, BS EN 344, etc.

This water Vapour Permeability testing machine consists of a Climate chamber, bottles, a rotatable disc used for holding the bottles. A powerful fan that can rotate at the rate of (1400 ± 100) r / min.

To carry out the test of water vapor permeability, you will need the following tools or accessories.

  • Silica gel desiccant (provided by Amadetech)
  • Balance (Accuracy nearest 0.001g)
  • Pre-flexing apparatus (Bally Flexometer) (prepared by the user or purchase from us)
  • Oven, Silica gel desiccant needs to be dried at least 16h at (125 ± 5)℃ (prepared by the user or purchase from us).
