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. 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.
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.
Troemner's Electronic Balance Calibration Weights are manufactured from the highest quality stainless steel alloy, possessing closely controlled density, low magnetic susceptibility, good stability and resistance to corrosion and damage through handling. All of Troemner's Electronic Balance Calibration Weights are type II which have an adjusting cavity to allow for adjustment during future calibrations. Within the weight there is a cavity that is filled with adjusting material, typically the same material from which the weight is made. This cavity is sealed during the production process to ensure the stability of the weight. Electronic Balance Calibration Weights are cylindrical in shape and flat on top, to stack easily on center.
Weights from 10 g to 500 g are machined as straight cylinders with the adjusting cavity opening in the bottom of the weight. Cylindrical weights from 1 kg to 5 kg are machined as cylinders and have a groove around the diameter approximately 25% from the top of the weight to allow for easier handling. The adjusting cavity opening is in the bottom of the weight for the 1 kg weight and on the top of the weight for the 2 kg through 5 kg.
Grip handle weights from 5 kg to 30 kg have a recess in the top center of the weight with a lifting handle spanning the recess slightly below the top surface of the weight. The recess allows the user to pick up the weight using the handle and provides clearance for the user's hand. Grip handle weights 5 kg to 10 kg are 5 inches in diameter. Grip handle weights above 10 kg to 30 kg are 6 inches in diameter. The adjusting cavity for grip handle weights is within the lifting handle.
Weights have all surfaces polished to a perfect, mirror like finish. Surface finish for Troemner UltraClass meets or exceeds ANSI/ASTM E617 Class 1 specifications.
To safeguard your Electronic Balance Calibration Weights, impact resistant polypropylene weight cases are provided with 10 g to 5 kg weights. These self-hinged cases have snug-fitting foam interiors to protect weights when not in use. A white cotton glove for handling weights is provided in each case or carton.
