Leather Testing Equipment Water Vapor Permeability Tester - China

price: 1.00 Dollar US$

Water vapor permeability tester is for measuring the water vapor permeability of leather or synthetic materials for shoes or personal protective equipment.

The tester provides certain rotary speed for holder and timer for counting the rotating number.

The operator can calculate the water vapor permeability by weight changes of desiccants.

It is widely used to determine the wearing comfort performance for shoes or personal protective equipment.

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 20C 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.
