Technique d'enregistrement automatique de pr�cision pour de faibles consommations d'oxyg�ne

摘要: The apparatus described permits the recording of very small volums oxygen in range 1 μl O2. consumption is measured by combination a volumetric method and electrical charge measurement. While used here for study fishes, this automatic recorder may be great variety organisms, animals or plants. ameliorations achieved various technics make it possible to obtain precision sensitivity volume variation detection, assurance that each impulse received corresponds really one second electrolysis return zero takes place without occurrence following electrolysis. Therefore an easy reading obtained.
