The Ohaus Model 311-000 Cent-O-Gram® Overhead Mechanical Balance has four beams to easily determine mass. This balance offers the accuracy and convenience of an integrated weigh-below balance while allowing students to visualize mass measurement principles. The hanging pan system offers ten times the readability of Ohaus triple beam balances. For a similar model with greater readability see the Dial-O-Gram® top-loading balance (item # H-310-000).
Features include a self-aligning beam design, special floating agate bearings, a counter-balancing knob to provide quick zeroing, and magnetic damping for quicker results. This durable balance is made with aluminum pressure casting for the base and beam assembly and has a removable stainless steel pan. Dimensions: 360 mm (14.2 in) L x 166 mm (6.5 in) D x 249 mm (9.8 in) H. Weight: 1.4 kg (3.1 lb).
Maximum capacity: 311 g. Readability: 0.01 g. Pan diameter: 89 mm (3.5 in). Pan height: 13 mm (0.5 in). Beams: 4. Test weight: 300 g, OIML F2 or ASTM CL 4.
