Henry Troemner Brass Calibration Test Weights

Troemner Brass Weights and Weight Sets are economical, quality weights for educational use. Individual weights are available from 2000 g to 1 mg. Weight Sets are designed to achieve any total mass by combining smaller masses. The makeup of Brass Weight Sets varies. Weights are adjusted to tolerances specified by ANSI/ASTM E617 Class 6. Brass Weights are provided in three designs; standard, hooked, and slotted to meet all educational needs. Slotted and Hook Weights are also available in Newton denominations from 0.1 N to 10 N (5 N for Slotted Weights).

Troemner Brass Weights

Construction and General Shape
Standard Design Weights - Weights 1 g and above are carefully manufactured of lacquered brass and are cylindrical in shape for easy gripping. Weights 1 g to 100 g are of one-piece construction and are adjusted during manufacture by removing material from the bottom of the weight. Weights 200 g through 2 kg have an adjusting cavity on the top that is sealed with a plug. Brass weights 1 g and above are perfectly flat on top to stack easily on center. Weights 500 mg and lower are made of sheet metal and are one-piece construction with one side turned up to make them easy to handle with forceps. 500 mg and 200 mg weights are made of stainless steel while weights 100 mg and below are made of aluminum.

Slotted Weights 10 g to 500 g (0.1 N to 5 N) are made of brass, and weights 1 g to 5 g are made of aluminum. All Slotted Weights have an approximate diameter of 1 5/8 inches and have a slot opening width of 1/4 inch. A hanger is also available from which you can stack and hang your slotted weights. The overall length of the hanger is approximately 7 7/8 inches with a useable length of 7 inches. The hanger is designed to accept the slotted weights.

Hook Weights range from 10 g to 1 kg (0.1 N to 10 N) and are made of brass. On all Hook Weights, except the 10 g, there is a hook on the top and the bottom of the weight so the weights can be hooked together. The 10 g (0.1 N) Hook Weight has a hook on the top only. The design of the Hook Weight allows the bottom hook to be recessed in the bottom, so the hooked weights can be set on a flat surface without tipping over. The opening of the hook for each weight is 1/2 inch.

All Brass Weights regardless of design are marked with their nominal mass value.

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.	Example
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.	Example
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.	Example
