This Mechanical Triple Beam Balance has an initial capacity of 610g, but the capability of achieving a capacity of 2610g with the included masses; 500g mass and 2 1000g masses. The tare knob allows for fine-tuned adjustments that result in an accuracy of 0.1g. Record measurements by moving the three sliding weights of 500g, 100g, and 10g along the tiered and grooved beams. The deep grooves prevent shifting and the advance magnetic dampening system brings the pointer to rest with a minimum number of swings. The metal base provides required durability for use in a classroom or lab.
