The present invention provides a specific methanogenic activity measuring apparatus, in which a carbon dioxide gas absorbing container 6 is removably accommodated in a pres-sure vessel 4 with a cover 3 removably set thereon, the pressure vessel 4 is removably accommodated in a thermostat-ic water bath 7 with a pressure transducer 8 based on the pressure-electricity converting system connected to a recorder 5 attached to the cover 3, and further a supporting member for supporting a carbon dioxide gas absorbing con-tainer and a generated gas piping 16 are attached to an external bottom surface and an internal bottom surface of the carbon dioxide gas absorbing container 6 respectively, and gas piping 12 with valves for gas phase replacement to the cover 3 of the pressure vessel 4.
La présente invention concerne un instrument de mesure de l'activité de méthanation constitué de plusieurs éléments. Un récipient pressurisé (40) est équipé d'un couvercle (3) amovible. Un vase d'absorption de dioxyde de carbone (6) est monté amovible dans le récipient pressurisé (40). Un réservoir d'eau thermostaté (7) est capable de recevoir amovible le récipient pressurisé (40). Une sonde manométrique (8) de type mano-électrique raccordée à un enregistreur (5) est fixée sur le couvercle (3). Un organe support pour le vase d'absorption de dioxyde de carbone et un tube à gaz produits (16) sont respectivement fixés sur les faces de fond extérieure et intérieure du vase d'absorption de dioxyde de carbone (6). Enfin, un tube de ventilation (12) portant une soupape à substitution de phase gazeuse est fixé au couvercle destiné au récipient pressurisé (4).
