Analytical balances are laboratory weighing balances designed to measure small mass in the sub-milligram range. The measuring pan of the analytical balances is inside a transparent enclosure with doors so that dust does not collect and affect the balance's operation. This enclosure is often called a draft shield. The weighing system used in Analytical Balances is the Electromagnetic Force Restoration system.
Precision Balances are also laboratory balances designed to measure relatively small to medium mass. The range offered by Precision Balances depends on the model and can range from 0.001g to 20,000g. The weighing systems used in Precision Balances are either the Electromagnetic Force Restoration system or the High Resolution Strain Gauge Load Cell system.
The M series of Precision Balances use the Electromagnetic Force Restoration System.
The L and S series of Precision Balances use the High Resolution Strain Gauge Load Cell System
Electromagnetic Force Restoration scales utilize a technology that measures electromagnetic force opposing the weight of the load. Electromagnetic Force Restoration scales are often used in analytical and laboratory applications.
Electromagnetic Force Restoration scales provide a higher level of accuracy than the accuracy provided by other technologies. For lower capacity loads, such as for use in laboratories, Electromagnetic Force Restoration scales offer much better accuracy than most and hence, are preferred.
