Abstract
The invention is concerned with a method for manufacturing a channel device, especially for recordings of thermal conductivity, viscosity, density, dielectric constants, refractive indices, etc. of materials such as fluids and gases (called samples), where the material under investigation is guided through a measuring channel with at least one sensor and at least one inlet and one outlet orifice for the sample. The invention also concerns the fabrication procedure of the channel device, especially the recording unit for determining the thermal conductivit, viscosity, density, dielectric constant, etc. of samples where the material under investigation is passed through or brought into a measuring channel which is equipped with sensors and actuators.
