SONO Vario Standard Moisture Sensor that we put forward is an ideal device to measure abrasive materials such as gravel, sand, and various other aggregates. It is very much reliable whenever utilized for measuring complex materials. Owing to small size and lightweight, it is simple to install in shaft, silos, containers and conveyor belts. The SONO Vario Standard Moisture Sensor has probe head, which consists of SS with a rectangular ceramic window. Moreover, measured radar-based conductance up to 12dS/m allows decisions on various other parameters of the material recipe.
