Calibration Masses

Calibration Masses

For precision weighing, select from either electronic or precision analytical balance masses. Electronic balance masses are cylindrical shaped for easy stacking on balance weighing pans. Precision analytical masses feature two-piece construction and consist of a special austenitic alloy for high precision and stability. Both groups of masses meet ASTM Class 1 or ASTM Class 4 standards, and are available with either a *NVLAP Lab Code 105013-0 (National Voluntary Laboratory Accreditation Program) or traceable certificate. For commercial applications, choose an NIST Class F weight. Use the descriptions below to select the best calibration class for your application.

UltraClass

With weight tolerances 50% greater than ASTM E617 Class 1 tolerances, these weights combine high precision with the advantage of two-piece construction (1 g and larger), avoiding costly replacement issues associated with one-piece weights.

ASTM Class 1

Appropriate for calibrating high-precision analytical balances with a readability as low as 0.1 mg to 0.01 mg.

ASTM Class 4

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

NIST Class F

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 III L or IIII, and scales not marked with a class designation.

ASTM Class 6

Meet the specifications of OIML R 111 Class M2.
