Abstract
An analytical device for determining the gas consumption of matter, specifically the oxygen demand of organic matter includes a container for holding the sample which is to be analyzed and a cop to seal the container gas-tight. Electrical and/or electronic measurement components are integrated in the cap. These components include an electrical pressure sensor which communicates with the interior of the container through a pressure connection, electronic measuring circuitry to which the pressure sensor output signal is sent in order to calculate a value which is proportional to gas consumption, keys for operating the electronic measuring circuitry, and a display for displaying measured, calculated, or stored values. The cap also contains a power source for the electrical/electronic components.
