General Information
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).
ANSI/ASTM E617 Class 6 Tolerances
Please see the Tolerance Chart within the Mass Standards Handbook for
specific information on the tolerance of each weight. For Newton Weights,
use the closest corresponding metric tolerance.
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.
Surface Finish
As outlined in ANSI/ASTM E617, all Brass and Aluminum Weights have a satin
finish. Brass Weight surfaces are protected with a coat of lacquer. For
ANSI/ASTM E617 surface finish specifications see the Mass Standards Handbook
on the website.
