A discrete bioelectrical impedance identification apparatus, comprising: a control means (1), which consists of a housing (11) and a control processing circuit (12) provided within the housing (11), the housing (11) being provided with a conductive point (111) partially exposed out of the housing (11), and the conductive point (111) be electrically connected to the control processing circuit (12) and a detection means (2), which comprises a probe (21) and a connecting rod (22). An accommodation cavity for receiving the probe (21) is formed within the connecting rod (22) so that the connecting rod (22) is fitted over the probe (21), and the end of the connecting rod (22) distal from the probe (21) is provided with a conductive needle (221) one end of the conductive needle (221) is electrically connected to the probe (21), and the other end is electrically connected to the control processing circuit (12) by abutting against the conductive point (111) the housing (20) is fixedly connected to the connecting rod (22) by using a detachable connection mode when the housing (20) is fixedly connected to the connecting rod (22), the conductive needle (221) abuts against the conductive point (111) and when the housing (20) is separated from the connecting rod (22), the conductive needle (221) is separated from the conductive point (111). The bioelectrical impedance identification apparatus is able to improve the utilization rate of products and reduce use costs.Linvention concerne un appareil didentification dimpédance bioélectrique discrète, comprenant : un moyen de commande (1), qui est constitué dun boîtier (11) et dun circuit de traitement de commande (12) disposé à lintérieur du boîtier (11), le boîtier (11) étant pourvu dun point conducteur (111) partiellement exposé hors du boîtier (11), et le point conducteur (111) étant électriquement connecté au circuit de traitement de commande (12) et un moyen de détection (2), qui comprend une sonde (21) et une tige de liaison (2
