Abstract

The device comprises, electrically connected in series, a current source, a recording instrument and electrodes (1). The electrodes (1) are fixed, with their ends, in a dielectric plate (2) provided with a holder. The device can be most effectively used when manufacturing the casting moulds and cores made of compounds which contain electrically conductive binding materials as well as of compounds hardening during thermal drying.
