GALILEO 9900P

Continuous gamma monitoring of materials on conveyors

System for continuous gamma monitoring of moving materials, for example on conveyors, with a large plastic scintillator. It is used mainly for scrap metal, steel plates and foundry dust but suits any application where moving material must be monitored. The stainless-steel detector box is mounted above or under the conveyor and managed from a panel PC.
