摘要:
The present invention pertains to an electronic measuring cell for detecting components in fluid media. Such a measuring cell is to be improved such that hermetic sealing of the contact wires leading out of the measuring cell is possible in a housing of a slightly modified design to prevent electrolyte from escaping. To achieve this, an annular space extending in parallel to the circumferential direction of the housing between the measuring cell cover and the housing is filled with an electrolyte- and temperature-resistant sealing material, and the contact wires are led through.

A device (1) and a corresponding method are provided for determining and/or monitoring the respiration rate based on measurement with more than one sensor (5, 7, 9, 13, 15). The device may be part of a monitor for determining and/or monitoring the respiration rate. The second and/or additional sensors are different form the first sensor and have a different manor of operation from the first sensor.
