Device for measuring the concentration of a chemical substance in fluid |
摘要 |
<p>The invention provides a device for measuring the concentration of a chemical substance in fluid, characterized by a semiconductor containing a measuring surface, the impedance magnitude of which alters on contact of the surface with the chemical substance and which is arranged in a housing in which is arranged a flow channel for the fluid, and wherein the measuring surface forms part of the wall of the channel and is sealed relative to the housing by means of a releasable sealing element, and which semiconductor is provided with electrical conductors for conducting the measuring signals. The releasable sealing element is preferably an O-ring. <IMAGE></p> |
