Abstract

Déteteur ionique à deux chambres d'ionisation 1 et 2, dites de mesure et de référence, raccordées électriquement en série et disposées de part et d'autre d'un circuit électroni­ que 6 monté sur un support 5 bon conducteur de l'électricité et auquel les électrodes des chambres, une source de tension et un dispositif avertisseur sont connectés, les éléments de ce circuit étant noyés dans une résine à très haute résistivité et comprenant un anneau de garde 17 dont une boucle 18 est disposée, à l'extérieur de la masse de résine 7, dans la chambre de mesure 1 et qui est porté au potentiel inverse de celui du support 5.
