mass weights

Calibration is determining the errors in a device relative to a standard, calculating a correction factor, and correcting the errors. Precision weight kit meet the requirements of one of the four classes. Use Class 1 and Class 2 weights as standards for calibration of analytical balances, in the calibration of lesser class weights, and as counterweights with analytical balances.

Use Class 3 and Class 4 weights as working weights and for calibration of general-purpose balances. General-purpose Set Weights are also known as Class F weights. Use Set as counter-weight in general-purpose balances and to calibrate scales to commercial tolerances. Most chrome plated, brass, and cast iron weights are general-purpose weights.

troemner set weights class e1 oiml

Troemner OIML Weight Sets are supplied in a 5-2-2-1 series. 5-2-2-1 series means that weights beginning with a "2" are doubled in each decade and weights beginning with a "5" and "1" are single in each decade. For example, for a set with 5-2-2-1 series from 50 g to 1 g, there is one 50 g, two 20 g, one 10 g, one 5 g, two 2 g, and one 1 g. The OIML Weight Sets Configuration Table that follows shows the contents of each set.
