The GranuCharge measures automatically and precisely the quantity of electrostatic charges created inside a powder during a flow in contact with a selected material.
The powder sample flows inside a vibrating V-tube and falls in a uniquely designed Faraday cup connected to an electrometer.
The electrometer measures the charge acquired by the powder during the flow inside the V-tube. To obtain reproducible results, a rotating or a vibrating device is used to feed the V-tube regularly.
