Liquid analysis apparatus, e.g. for polluted water, has sensor located in cavity separated from through flow channel by semi permeable medium
The sensor and calibration device are located in cavities (3-7) in a casing (2) containing a through-flow channel (8) for the liquid being analyzed. The sensor cavity (3, 4) is separated from the through-flow channel by a semi-permeable medium (9). An analysis apparatus (1) for detecting substances...

| Zusammenfassung: | The sensor and calibration device are located in cavities (3-7) in a casing (2) containing a through-flow channel (8) for the liquid being analyzed. The sensor cavity (3, 4) is separated from the through-flow channel by a semi-permeable medium (9). An analysis apparatus (1) for detecting substances dissolved in a liquid comprises at least one substance-specific sensor for bringing into contact with the liquid and a sensor calibration device for the sensor. The sensor and calibration device are located in cavities in a substantially solid casing containing a through-flow channel for the liquid being analyzed. The cavity for the sensor is separated from the through-flow channel by a semi-permeable medium and bordered elsewhere by at least one layer of electrically insulating material. |
