Themeasuringsystemof theMM400isbasedonanadvanced MICROPROCESSOR technology that detects the percentage of moisture held by the aggregates, through specific sensors installed in the weigher or in the storage hoppers.
The instrument can analyze the humidity in 4 AGGREGATES with different diameters: small, medium or large ones. Through a special configuration menu, it allows selection of the most suitable diameter-curve from among themostcommononesusedintheconcreteindustry,foreasyand straighforward setup.
