Description
Precision Analytical Individual Weights - Metric
Weights are manufactured from the finest materials including Troemner Alloy 8 and are manufactured in sizes ranging from 1 mg through 50 kg. Weights are available in Troemner UltraClass Platinum, UltraClass Gold, UltraClass and ANSI/ASTM E617 Class 000*, 00*, 0, 1, 2, 3 and 4.
Weights are designed so the specifications on surface finish, markings, construction, material density, and magnetic properties become more restrictive as the weight tolerances decrease in order to enable the weight to maintain its tolerance over time. These weights are designed for your most demanding weighing applications.
Suggested markets for Analytical Precision Weights include, but are not limited to, pharmaceutical, forensic and nuclear industries.
Class
UltraClass Platinum
The weight tolerance is equal to ANSI/ASTM E617 Class 000 and OIML R 111 Class E0. 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 0.0001 mg.
UltraClass Gold
The weight tolerance is equal to ANSI/ASTM E617 Class 00 and 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.
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 weights and is appropriate for calibrating high-precision analytical balances with a readability as low as 0.01 mg.
Class 000
Used as a primary reference for calibrating other reference standards and weights. Class 000 weights are intended to be used in metrology laboratories where the stability of the environment and careful handling are assured. Although very stable, one-piece construction Class 000 weights have no method of adjustment and are not suitable for general laboratory use. Class 000 is 1/2 the tolerance of Class 00 and the uncertainty is the best measurement reported in our NVLAP (Laboratory Code 105013-0) Scope of Accreditation which is guaranteed to be 1/3 the tolerance or better. Class 000 is pending approval of ANSI/ASTM E617.
Class 00
Used as a primary reference for calibrating other reference standards and weights. Class 00 weights are intended to be used in metrology laboratories where the stability of the environment and careful handling are assured. Although very stable, one-piece construction Class 00 weights have no method of adjustment and are not suitable for general laboratory use. Class 00 weight tolerances are equal to OIML R111 Class E1 tolerances and are tighter than Class 0. The uncertainty is guaranteed to be 1/3 of the tolerance. Class 00 is pending approval of ANSI/ASTM E617.
Class 0
Used as a primary reference for calibrating other reference standards and weights. Class 0 weights are intended to be used in metrology laboratories where the stability of the environment and careful handling are assured. Although very stable, one-piece construction Class 0 weights have no method of adjustment and are not suitable for general laboratory use. The uncertainty is guaranteed to be 1/3 the tolerance.
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
Appropriate for calibrating high-precision top loading balances with a readability as low as 0.01 g to 0.001 g.
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
For calibration of semi-analytical balances and for student use.

Certificate
NVLAP Accredited Certificate
Troemner's NVLAP Accredited Certificate provides compliance in both measurement process and data reported to the customer to meet a variety of standards including NVLAP Handbook 150-2, ISO/IEC 9000, ISO/IEC 17025, FDA, GMP. GLP, DOD, ANSI/NCSL Z540-1 and nuclear requirements. Troemner's NVLAP Laboratory Code is 105013-0. The NIST administered National Voluntary Laboratory Accreditation Program (NVLAP) approves, through periodic audits, all processing and weighing procedures, as well as certificate format and content. Calibration procedures vary by tolerance class requested. For example, for higher accuracy classes such as Troemner UltraClass Series, ANSI/ASTM E617 Class 000, 00, 0 and 1, OIML R 111 Class E0, E1, E2 and F1, Troemner performs a multiple weighing procedure utilizing standards to determine the mass of a customer's weight.

Traceable Certificate
The Traceable Certificate is designed for those laboratories and companies that require traceability but do not need to meet any stringent regulatory requirements. The Traceable Weight Certificate measurement process is based on a single standard and utilizes one series of comparisons.
