NEW SHORT BEAM ANALYTICAL BALANCE
577—F. E. BECKER & Co.’s NEW SHORT BEAM ANALYTICAL BALANCE, for quick and accurate weighing. The Beam is of new design, with white graduations along its entire length and manufactured by a spécial process from a métal which is not influenced in any way by température variations and is also particularly designed to prevent stresses, etc. The rider apparatus traversing the whole length of the beam is of an improved, simple but efficient type, spécial attention having been given towards minimising the risk of riders falling during operations. The knife-edges and planes are of best quality agate throughout, the knife-edges being fitted with our patent mountings thus ensurmg easy replacement should occasion arise. The case is extra large and roomy of superior polished mahogany with glass top, two side glass doors and sliding counterpoised front window, the whole being mounted on a heavy thick black glass base with massive brass levelling screws and spirit level.
Capacity : 200 grammes in each pan. Sensitivity : Tü milligramme when carrying full load.
