Device for measuring chemical and physical parameters of a liquid or gaseous medium
First Claim
1. A device for measuring chemical and physical parameters of a fluid medium, said device comprising:
- a supporting frame which is connectable to an input line for fluid medium and to an output line for fluid medium,a measuring unit insertable into said supporting frame to define a sample channel for fluid medium flowing between said input line and said output line, said measuring unit comprising a sensor carrier defining a flat surface facing said sample channel and including a bore therethrough,an optode having a indicator film positioned in said bore of said sensor carrier such that said indicator film is positioned in said plane of said sensor carrier and in communication with fluid medium flowing through said sample channel, andmeans for optically exciting said indicator film of said optode and for detecting and evaluating optical signals emitted therefrom so as to measure chemical and physical parameters of said fluid medium.

Abstract
In order to reduce the measuring volume in a device for measuring chemical and physical parameters of liquid or gaseous media by means of optical sensor elements whose optodes may be replaced easily, a measuring unit with a sample channel is provided which may be inserted into a supporting frame of the device and which may be connected to ingoing and outgoing sample lines via capillary bores. The measuring unit contains a sensor carrier forming the boundary of the sample channel on one side, which sensor carrier has bores holding the optodes. The indicator film of each individual optode is situated in the plane of the sensor carrier facing the sample channel.
