Mass Standards Handbook

Troemner's proprietary Mass Standards Handbook is a useful reference for all metrology laboratory personnel.   This Handbook is designed to clarify the applications, classifications and physical characteristics of precision weights and mass standards and the tolerances used in their production and calibration.  Anyone who uses balances, scales and associated calibration weights/weight sets in their work will find this publication a helpful and practical aid.

Troemner Stainless Steel Analytical Weights

  For your most precise weighing needs, Troemner's analytical weights are essential. These weights are manufactured from stainless steel bar stock chosen for its uniform density , high resistance to wear and corrosion, and low magnetic properties to produce the finest weights available.

Troemner produces this style weight in two configurations, one-piece and two-piece. While both are manufactured to meet or exceed tolerance specifications for their class, one-piece weights should be used when the application calls for reference standards or when maximum stability is required. A precise measurement of density can only be made with a one-piece mass standard. For calibration applications, two-piece weights offer the advantage of being repairable and can be adjusted by Troemner's metrology laboratory over time.

Troemner Electronic Balance Weights

   To get the full accuracy your electronic balance/scale provides, you need to perform routine calibrations and adjustments using precision calibration weights. Troemner offers stainless steel calibration weights manufactured especially for this purpose. Weights are available in cylindrical and stackable grip-handle configurations for all necessary testing, calibration and adjustment of electronic scales and balances. Troemner's electronic balance calibration weights are adjusted in strict accordance with standard ANSI/ASTM E617.

Troemner Stainless Steel OIML Weights

   Ideal for your high precision weighing needs, Troemner OIML weights conform to the standards of the Organization Internationale de Metrologie Legale (OIML) International Recommendation R 111. They are manufactured of stainless steel with low magnetic permeability and high resistance to corrosion. All surfaces are polished to a perfect, mirror like finish to form the finest weights available.

As specified in R 111, Troemner's OIML weights are available in one or two piece configurations. One piece weights meet tolerance classes E1 and E2, while two piece weights meet F1, F2, and below. Milligram OIML weights are available in two styles - flat, with one side turned up to form a handle, and wire with a hollow center for easy gripping.

Troemner OIML weight sets - 500 grams and higher - are supplied in strong oak cases and are fully lined with padded velvet or velour. Weight sets 200 grams and lower and all individual weights come in attractive, sturdy plastic cases.

Troemner Brass Weights

Brass Weights   Troemner manufactures economical, high quality brass weights and weight sets that are ideal for general laboratory, industrial, technical and educational use. These brass weights and weight sets are designed for all routine weighing where ultra-precise tolerances are not required, but where economy is essential.

These weights are carefully manufactured of lacquered brass or of stainless steel. These weights are adjusted according to ANSI/ASTM, NIST or OIML specifications depending upon our customer's requirements. For the protection of the weights, Troemner includes a rugged carrying case with these weight sets.

Troemner Class F Test Weights

Class F Test Weights   Troemner stainless steel test weights are available for work with balances of less precision and accuracy. These weights are intended to be used primarily to test commercial weighing devices for compliance with the requirements of NIST Handbook 44. The weights are calibrated according to NIST Handbook 105-1 specifications for Class F.

Troemner's test weights are available in a variety of denominations including metric, avoirdupois, grain, troy and pennyweight. Troemner has also designed test weights in different shapes such as cylindrical, cube, stackable grip handle, slotted and hook styles to meet your unique weighing applications.

Troemner Cast Iron Weights

Troemner's cast iron weights are legal for trade, and are available up to 2000 kg or 5000 lbs. These weights are used to examine devices used in commerce, as reference standards in state weights and measures laboratories and in industrial, educational, and research laboratories. Smaller cast iron weights are available in slotted styles that can be used with a weight hanger. Troemner's cast iron weights meet Class F specifications and tolerances which are listed in NIST Handbook 105-1.
