Balance Hood

The BH550 (previously WS110) is a dual purpose extraction hood that protects personnel from nuisance media powders and also protects the balance from air turbulence.

The standalone unit is designed to easily fit onto most benchtops and is ideally suited for those in-between applications which are too small to necessitate a fume cupboard but benefit from improved containment.

This unit is suitable for analytical balances.  It comes flat packed and is very easy to assemble
