Dry Matter Measurement Systems From Berthold Technologies

The dielectric constant of water is more than 20 times larger compared to other materials. This results in a strong interaction of the microwaves with water, which is then measured as phase shift and attenuation. In this way, the dry matter content can be determined very accurately. Another significant advantage in comparison to other methods for dry matter measurement is that the microwave technology is hardly affected by factors such as viscosity, color or inhomogenous material composition. The equipment works with very weak microwave power (typically around 0.1 mW) so that the material being measured is not heated or altered in any way.
