Manufactured from stainless steel. The Troemner™ Stainless Steel Class 7 Weight Set is used for rough weighing operations in physical and chemical laboratories.

Made of vacuum melted steel for highest material purity

Economical, quality weights

Meets ASTM Class 4 adjustment tolerances and is ideal for applications requiring a degree of accuracy above general purpose weights

Primarily used to test commercial weighing devices by state and local weights and measures officials, device installers and service technicians. Class F weights may be used to test most accuracy Class III scales, all scales of Class IIIL or IIII, and scales not marked with a class designation.

Low magnetic permeability and high corrosion resistance for reliable stable values

Combine high precision with the advantage of two-piece construction. UltraClass weights, exclusive to Troemner™ are the most precise two-piece weights available with weight tolerances that equal ANSI/ASTM E617 Class 0 or OIML R 111 Class E2 tolerances.

For routine testing of balances

For rough weighing operations in physical and chemical laboratories, such as force measuring apparatus.

High quality brass balance weights for use in calibration or as replacements for balance weight sets. Weight etched on top.

Adjusted to Meet or Exceed ASTM Class 4 Tolerances

Class 1, calibrated weights ranging from 1 mg to 200 g

Meet or exceed tolerances established for Class F in NIST Handbook 105-1

Made of vacuum melted steel for highest material purity

Explore weight and measurement with these easily stackable Hexagram Weights.

F1 OIML quality weight set housed in a plastic case includes accessories for handling and cleaning, and a calibration certificate.

F1 OIML class weight set housed in an aluminum box includes accessories for handling and cleaning, and a calibration certificate.

Standard Line Weights. Specially used stainless steel, including the mg range, ensures anti corrosive surfaces with low magnetization and susceptibility values. Solid, one piece construction and mirror-polished surface grades give stable values.

Higher process safety for more efficient testing

Low magnetic permeability and high corrosion resistance for reliable stable values. Calibration certificate not included.

E2 OIML class weight set is housed in an aluminum box and includes accessories for handling and cleaning.

Precision-crafted of stainless steel, with a highly polished finish

ASTM precision weights, Best Price-Performance Ratio. Low magnetic permeability and high corrosion resistance ensure reliable values. All weights are made with stainless steel.

Individual weights

Combine high precision with the advantage of two-piece construction with the most precise two-piece weights available with weight tolerances that equal ANSI/ASTM E617 Class 0 or OIML R 111 Class E2 tolerances.

For use with a variety of mechanical scales. OHAUS™ Triple Beam Balance Mass Set includes two 1kg and one 500g counterweights for use with compatible Triple Beam 700 series, Dial-O-Gram 1600 series and Pro series mechanical balances.
