Device for determining surface moisture |
摘要 |
A device for determining surface moisture, especially of absorbent materials, comprises a Dove reflection prism, a radiation source of such a design that its beams, which are aligned parallel, perpendicularly strike one of the two small surfaces of the prism, a light trap which traps the light beams emanating from the other small surface, and a photoelectric transducer which is located in the angle formed by the two small surfaces and is arranged such that its measurement surface is located parallel and opposite to the hypotenuse surface of the prism.
