Principles of operation

‘Torbal’ balances have several advantages over other balances based on the following principles: 1) The mechanism is virtually in one piece, and no parts move over other parts – in consequence, no wear occurs; 2) There is no knife edge fulcrum to dull with use and by the action of the dust and abrasives common in laboratories; 3) Movement is friction free and there are no bearings to become sluggish with accumulated dust; 4) The absence of loose parts means that adjustments are permanent; 5) The basic advantages of a ‘Torbal’ Balance-quick action and sensitivity to small weight differences; 6) are maintained throughout the life of the balance.
