Applications:
Leather Water Vapor Permeability Tester is mainly applicable to leathers and textiles used in footwear uppers and clothing where it gives a measure of the ability to remove perspiration from the surface of the wearer's skin.The tester is used to determine the amount of water vapour a material will transmit through its structure in a specified time.

Product information:
The vapor permeability of leather is evaluated by means of measuring the weight of water-vapor that permeates to specimen per unit time and per unit area. The main functional components includes: testing holder clamp, ventilation fan, control panel with functions of switch, time setting and recording.
The machine has six separate test stations on a rotary table and each one has a sample holder. Silica gel desiccant is placed in the holder and the test material is placed over the neck of the holder and secured by a screw top. After weighing each holder, complete with silica gel and sample material, the holders are placed and locked into the rotary mechanism. After 7-8 hours the complete holder is weighed again and the gained weight is used to determine the degree of permeability. It is essential that the entire operation is carried out in a conditioned atmosphere of 20°C and 65% per cent relative humidity. In addition to the standard equipment, the tester is also supplied with a built-in timer to record the number of hours that testing has been carried out.
