Une cavité de réception pour recevoir la sonde (21) est formée à l'intérieur de la tige de liaison (22) de telle sorte que la tige de liaison (22) est ajustée sur la sonde (21), et l'extrémité de la tige de liaison (22) distale par rapport à la sonde (21) est pourvue d'une aiguille conductrice (221) ; une extrémité de l'aiguille conductrice (221) est électriquement connectée à la sonde (21), et l'autre extrémité est connectée électriquement au circuit de traitement de commande (12) en venant en butée contre le point conducteur (111) ; le boîtier (20) est relié de manière fixe à la tige de liaison (22) en utilisant un mode de connexion détachable ; lorsque le boîtier (20) est relié de manière fixe à la tige de liaison (22), l'aiguille conductrice (221) vient en butée contre le point conducteur (111) ; et lorsque le boîtier (20) est séparé de la tige de liaison (22), l'aiguille conductrice (221) est séparée du point conducteur (111). L'appareil d'identification d'impédance bioélectrique peut améliorer le taux d'utilisation de produits et réduire les coûts d'utilisation.
