Nowadays, filtration barrier materials are more often used for providing with long-term protection of the Czech Armed Forces professionals and Fire Rescue Brigades specialists against the effects of toxic compounds. A comprehensive study provided authors with evaluation of their protective properties’ qualitative changes in connection with knowledge development of possibilities of sensor technologies at this time. A solution usable for an electronic detection of the moment of water permeation or a liquid phase of other test chemicals (penetration) through construction materials of a filtration type or permeable barrier materials which are or perspectively can be used for protection against the effects of toxic compounds has been recently proposed. The aim of the solution is to replace a current used subjective way of the visual observation of water or other test chemicals penetration through textile materials used in anti-gas protection with the objective observation of the moment of test chemicals permeation (time of drench) with the help of a conductivity sensor with a possibility of an automatic record of the rate of penetration with the employment of the KONDUKTOTEST device.
