Calibration Masses

Calibration Masses

  • For precision weighing, select from either electronic or precision analytical balance masses

Electronic VS Precision Analytical 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.

Class-000 UltraClass Platinum


UltraClass Platinum — The weight tolerance is equal to ANSI/ASTM E617 Class 000 and Class E0*. This class is used as a primary standard for calibrating other reference standards and weights where the stability of the environment and careful handling are assured. This class is appropriate for calibrating high-precision analytical balances with a readability as low as 0.0001 mg.

Class-00 UltraClass Gold


UltraClass Gold — The weight tolerance is equal to ANSI/ASTM E617 Class 00 and meets or exceeds OIML R 111 Class E1. This class is used as a reference standard for calibrating other reference standards and weights where the stability of the environment and careful handling are assured. This class is appropriate for calibrating high-precision analytical balances with a readability as low as 0.001 mg

Class-0 UltraClass


UltraClass — 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 is appropriate for calibrating high precision analytical balances with a readability as low as 0.01 mg.

Class 1

ASTM Class 1 — Can be used as a reference standard in calibrating other weights and is appropriate for calibrating high-precision analytical balances with a readability as low as 0.1 mg to 0.01 mg.

Class-2


ASTM Class 2 — Appropriate for calibrating high-precision top loading balances with a readability as low as 0.01 g to 0.001 g.

Class-3


ASTM Class 3 — Appropriate for calibrating balances with moderate precision and with a readability as low as 0.1 g to 0.01 g

Class 4

ASTM Class 4 — For calibration of entry level balances and for student use

Class 6

Cast Iron Slotted Weights are used in a variety of applications such as pressure, torque, and tensile strength testing. Cast Iron Slotted Weights are typically used with a hanger that also has its weight calibrated so the hanger can be used as part of the overall weight under test. Several Cast Iron Slotted Weights may be used together to build up from a minimum weight to a maximum test load. The hanger weight selected should be able to accommodate the total load needed.

Class-7


Economical Weights are available from 1 mg through 2000 g. Weights are adjusted to tolerances specified by ANSI/ASTM E617 Class 7. For entry level balances and student use.

Class-F Test Weights

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.

CalPak Calibration Weight Sets


Cal-Paks contain (3) high quality, precision weights which can be used with all balance manufacturers’ makes and models. The weights supplied are the balance manufacturers’ recommended calibration weight, 10% of the calibration weight, and the minimum weight as determined by the balance’s readability and expected standard deviation under normal conditions as recommended by USP 41 (United States Pharmacopeia).
