Abstract
A device for measuring volatile constituents of a culture medium in the fermentation industry, comprising a probe, which has a permeable membrane to exchange material for a carrier medium, and a sensor responding to the content of the substance to be measured which has permeated into the carrier medium. In order that the device may be used in industrial fermenters and in order to achieve a high degree of accuracy in measurement and reproducibility of the measured values, both the permeable membrane and the sensor are disposed in the space in which the culture medium to be tested is situated, the probe being introduced into the space containing the culture medium where appropriate by way of a lock.
