Weights for Triple Beam Balance (2000g)
Weights for Triple Beam Balance (2000g)
46892

Hanging metric weights used to extend scale capacity of Ohaus 750-S0 and 750-SW metric triple-beam balances (not included). Cast iron construction has durability and long life. The set of three attachment weights includes two 1,000g weights and one 500g weight.


Calibration weights are used to measure the weight or mass of an object using a balance or scale, or to calibrate other weights or instruments. Calibration weights can be certified or uncertified. Certified weights meet strict guidelines for accuracy and can usually be recertified. Certified weights are used in labs where a high degree of accuracy and repeatability is required. Uncertified weights are used where a lower degree of accuracy is required, including student laboratories, rough weighting operations, and measuring force. Hooked and slotted weights are often used to measure pressure, torque, and tensile strength, and to demonstrate basic laws of physics. Calibration weights differ from lab weights, which are general purpose weights used to hold an object in place, similar to a paperweight.
