Primarily used to test commercial weighing devices by state and local weights and measures officials, device installers and service technicians. Class F weights may be used to test most accuracy Class III scales, all scales of Class IIIL or IIII,

Class 4 For calibration of semi-analytical balances and for student use.

The weight tolerance is equal to ANSI/ASTM E617 Class 0 and exceeds OIML R 111 Class E2. This class is used as a reference standard for calibrating other reference standards and weights and is appropriate for calibrating high-precision analytical

These weights are manufactured Troemner Alloy 8 Stainless Steel, which was developed by Troemner and is available exclusively through Troemner. This unique material possesses low magnetic susceptibility, uniform consistency and high resistance to
