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 Electronic Balance Weights are intended for this purpose and are available in Troemner UltraClass Platinum, UltraClass Gold, UltraClass and ANSI/ASTM E617 Class 1, 2, 3, and 4 in sizes ranging from 10 g through 30 kg.
Weights are available in a cylindrical design up through 5 kg and a stackable grip-handle design from 5 kg through 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. Cases for weights 10 kg and above are available at an additional cost.
Electronic Balance Weights can 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.
Electronic Balance Weights are ideal for non chemical environments to verify balances or scales.
Available exclusively from Troemner, UltraClass Series weights are the most precise two-piece weights available with weight
tolerances that equal or exceed ANSI/ASTM E617 Class 000, 00, and 0 tolerances. Troemner UltraClass weights combine high precision with the advantage of two-piece construction avoiding costly replacement issues associated with one-piece weights.
Stainless Steel Electronic Balance Weights are adjusted to Troemner UltraClass Platinum, UltraClass Gold, UltraClass and ANSI/ASTM E617 Class 1, 2, 3, and 4.
It is recommended that the weight selected to calibrate a balance and/or scale have a tolerance small enough 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 0 or Troemner UltraClass Electronic Balance Weight with a NVLAP+ Certificate be ordered which provides the actual mass value for the weight which reduces measurement uncertainty.
Construction and General Shape
Troemner’s Electronic Balance Weights are manufactured from a high quality stainless steel alloy, possessing closely controlled density, low magnetic susceptibility, good stability, and resistance to corrosion. All of Troemner’s Electronic Balance Weights are made of two pieces and have a cavity that allows for adjustment during future calibrations. Within the cavity there is 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 Weights are cylindrical in shape and flat on top to stack easy on center.
Straight Cylinder Weights - Weights from 10 g through 600 g are machined as straight cylinders with the adjusting cavity opening in the bottom of the weight.
Cylindrical Weights - 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.
Grip Handle Weights - Grip handle weights from 4 kg through 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 4 kg to 10 kg are 5 inches in diameter. Grip handle weights above 10 kg through 30 kg are 6 inches in diameter. The adjusting cavity for grip handle weights is within the lifting handle.
Troemner UltraClass Series, as well as ANSI/ASTM Class 1, 2, and 3 weights all have surfaces polished to a perfect, mirror-like finish. ANSI/ASTM Class 4 weights have a satinlike appearance and finish. All surface finishes meet or exceed ANSI/ASTM E617 specifications. Surface finish for Troemner UltraClass Series meets or exceeds ANSI/ASTM E617 Class 0 specifications.
To safeguard your Electronic Balance Weights, attractive, durable, high quality, polycarbonate cases are provided with weights 10 g through 5 kg. The polycarbonate cases feature a custom insert, bumper, and locking lid to assure weights are held securely within the case and avoid movement. A nylon glove is provided with each weight. Polycarbonate cases for 10 kg weights are available at an additional cost.
Polypropylene cases with handles for larger Electronic Balance Weights 16 kg through 30 kg are available at an additional cost. These cases are made of high-impact plastic, reinforced with metal edges and corners and have a padded carrying handle.
Weights are available in almost all combinations of features. Please contact us for more information
