Controlling the relative air humidity during a measurement on a powder is important.
Particularly, during electrostatic measurement with the GranuCharge instrument.

Therefore, Granutools developed an air generator with fixed relative humidity called the GranuMidity.

This air conditioner can easily be coupled with the GranuCharge instrument, in order to perform
the measurements always at the same hygrometric conditions or also, at different humidity levels.
