摘要:
The present invention relates to an electrode sensor arrangement (1) with a flow cell (2) and a measurement electrode (3) arranged in said flow cell (2) for measuring a parameter of a fluid (5) flowing in said flow cell (2). The present invention further relates to a method for measuring a parameter of a fluid (5) by an electrode sensor arrangement (1). This inventive electrode sensor arrangement (1) further comprises a vibration device (6) to vibrate (10) said fluid (5) while said fluid (5) is flowing in said flow cell (2) to be measured by said measurement electrode (3). This inventive method for measuring a parameter of a fluid (5) comprises vibrating (10) said fluid (5) while said fluid (5) is contacting a measurement electrode (3), especially a measurement surface (7) of said measurement electrode (3), of said electrode sensor arrangement (1) to be measured by said measurement electrode (3).

摘要:
A handheld, small but accurate and reliable device for diagnostic NO measurements using a NO sensor, where the parameters governing the taking of the sample are different from the parameters optimal for the accuracy of said NO sensor is described. By temporarily storing a portion of the exhaled air, and feeding this to the sensor at a flow rate adapted to the NO sensor, the accuracy and sensitivity of a system and/or a method involving NO sensors, can be increased.

摘要:
Apparatus for monitoring the pH value of a substance, such as oesophageal pH of a person. The apparatus comprises means for measuring pH values, which is positioned in use in the oesophagus, and for providing digital output signal representative thereof. A portable data logging apparatus adapted to be carried by the person being monitored includes a store for storing the digital values at predetermined intervals and means is provided for analysing the stored signals during a defined period to provide a pH characteristic of the substance being monitored over the period.
