DRK641 Constant temperature and humidity chamber

Product details

Technical description of the instrument:

It is mainly used to measure the moisture permeability of all kinds of fabrics, including permeable coated fabrics. Structure principle: adopt computer control, creating a constant temperature, and humidity test environment, test environment in the constant temperature, and humidity, moisture vapor transmission cup, placed 6 sample into the glass and the rubber gasket seal, the containing hygroscopic agent or water seal is specified by the wet cup placed in the fabric sample temperature and humidity of the environment, the seal moisture vapor transmission cup according to a certain time (including sample and hygroscopic agent or water) to calculate the moisture transmission quality change.
