Henry Troemner Electronic Balance Calibration Weights

To get all the accuracy your electronic balance and/or scale provides, you need to perform routine calibrations and verifications using precision calibration weights. Troemner's Stainless Steel Electronic Balance Calibration Weights are intended for this purpose and are available in Troemner UltraClass and ANSI/ASTM Classes 1, 2, 3 and 4 in sizes ranging from 10 g to 30 kg. Weights are available in a cylindrical design up to 5 kg and a stackable grip-handle design from 5 kg to 30 kg for all necessary testing, calibration and adjustment of electronic scales and balances. All ANSI/ASTM E617 class weights meet or exceed specifications for tolerance, construction, surface finish, and magnetism as outlined in ANSI/ASTM E617. Weights 5 kg and below are supplied in protective cases.

Why UltraClass?
Troemner UltraClass weights are the most precise type II two-piece weights available with weight tolerances 50% greater than ANSI/ASTM E617 Class 1 tolerances. UltraClass weights combine high precision with the advantage of two-piece construction (1 g and larger) avoiding costly replacement issues associated with one-piece weights.

Suggested Applications
It is recommended that the weight selected to calibrate a balance and/or scale have a tolerance small enough as not to be detected by the balance and/or scale. Troemner recommends the tolerance of a weight selected for calibrating a balance and/or scale is no more than 1/3 of the readability or precision of the balance and/or scale being calibrated. If this cannot be achieved, it is suggested that a Class 1 or Troemner UltraClass Electronic Balance Calibration Weight with a NVLAP certificate be ordered which provides the actual mass value for the weight which reduces measurement uncertainty.

Electronic Balance Calibration Weights can also be used to check or verify the accuracy of your balance and/or scale between calibrations. It is recommended that the user check a balance and/or scale prior to each use. Keeping the weight at or near the balance and/or scale keeps the weight at the same temperature as the equipment.



Need a certificate with your Troemner weight? Please look over the following information to determine what certificate you need.

Troemner Certificate Matrix -- See which cert you need
NVLAP Weight Calibration Certificate NVLAP Weight Calibration Certificate is a detailed, multi-page weight certificate designed to meet all of your ISO (including ISO/IEC 17025), FDA, GMP, GLP, DOD, ANSI/NCSL Z540-1, and nuclear requirements. The NIST-administered National Voluntary Laboratory Accreditation Program (NVLAP Lab Code 105013-0) approves all procedures for this detailed weight certificate. The measurement process follows the recommendations of NIST Handbook 145.
Traceable Weight Certificate Traceable Weight Certificate - designed for those laboratories and companies that require traceability, but do not need to meet any stringent regulatory requirements. In contrast to NVLAP or UKAS calibration procedures, the Traceable Weight Certificate measurement process is based on a single standard and utilizes one series of comparisons.
Statement of Accuracy New weights and weight sets supplied without weight certificates come with Troemner's Statement of Accuracy which provides the nominal value, type of weight, material / density and weight class. Note: There is no NIST traceability supplied with this statement. The Statement of Accuracy is not suitable for quality or regulatory requirements. Troemner's Statement of Accuracy is only available with the purchase of new weights. Troemner's Brass Weights are not supplied with a Statement of Accuracy.
