Device for fixation of instant of penetration of chemically aggressive medium through polymers has dielectric case in which chamber with cover for aggressive medium under investigation is placed, and two electrodes one of which is made perforated, dielectric pad placed between electrodes, in openings of perforated electrode electro-conductive plates are placed, those are insulated from perforated electrode. As registration device capacitor indicator is used, with electrodes connected to it. To the cover of the chamber controller of supply of aggressive medium is mounted, this is connected to control block. Capacitor indicator is connected as well to control block controlling time counter. |
