Measuring electrodes (5, 6) are provided in the upper and lower regions of the sample container. A driving device moves sample fluid through the gap with predetermined flow velocity. A bore is provided in the sample container. The gap is formed between an inner wall of the bore in the sample container and a calibration rod (30), which is attached in the bore in a slack-free and removable manner.</p> |
