Industrial Standard Loose Weights - Limra Instruments, Vasai

Precision is a critical requirement across all industrial weighing operations, not just laboratory environments. Limra Instruments, Vasai, manufactures and supplies Industrial Standard Loose Weights designed to meet the demanding needs of calibration, verification, and load testing in heavy-duty industrial conditions.
Limra loose weights are engineered to deliver OIML- and NIST-traceable accuracy for high-capacity weighing systems. They support regulatory compliance, ensure measurement reliability, and help maintain consistent production quality across industrial operations.

Purpose and Advantages of Industrial Standard Loose Weights :

Standard loose weights are specifically designed for individual handling and repeated use in harsh industrial environments. Unlike enclosed laboratory weight sets, they offer flexibility and durability for high-capacity applications.
These weights are widely used for calibrating platform scales, dormant scales, and weighbridges, as well as for load testing of cranes, hoists, elevators, and lifting equipment. They also play a critical role in legal-for-trade verification and government stamping procedures followed throughout Maharashtra.

Range of Industrial Loose Weights :

Limra Instruments offers a comprehensive selection of Industrial loose weights in multiple designs and materials to suit specific industrial applications.

  • Cylindrical and Knob-Type Weights :
    Manufactured in polished stainless steel (SS-304 / SS-316) or high-grade cast iron, these weights provide excellent durability and corrosion resistance. The knob-type design allows safe handling by hand or with lifting tongs, making them suitable for industrial tabletop scales and medium-capacity platform scales.
  • Rectangular Grip-Handle Weights :
    These weights are produced from heavy-duty cast iron with a smooth powder-coated finish. The integrated ergonomic handle enables safe manual handling and transport. They are commonly used for calibrating floor scales and warehouse weighing systems and are available in standard capacities such as 5 kg, 10 kg, 20 kg, and 50 kg.
  • Slotted and Counterpoise Weights :
    Slotted and counterpoise weights are designed for flexible load configuration and can be stacked on hangers to achieve adjustable load values. They are widely used in mechanical testing, tension measurement applications, and traditional beam-type weighing systems.

Weight Classes and Technical Overview :

Limra Instruments supplies Industrial loose weights across multiple OIML accuracy classes to match different scale readabilities and industrial requirements.

  • Class F1 / F2 :
    Suitable for precision industrial scales with readabilities from 0.01 g to 0.1 g; manufactured from mirror-polished stainless steel
  • Class M1 :
    Intended for standard platform scales and commercial weighing systems; available in SS-304 or high-grade cast iron
  • Class M2 / M3 :
    Designed for heavy-duty load testing and general trade applications; manufactured from powder-coated cast iron

Loose weights are available in capacities ranging from 100 g to 500 kg, with customization options available on request.

Frequently Asked Questions

What are standard loose weights and how are they different from boxed weight sets?
Loose weights are sold individually rather than as part of a complete boxed set letting you buy only the denominations you need, replace a worn weight in an existing set, or build a custom range. If you need a 5 kg weight for one machine and a 10 kg for another, buying loose weights is far more cost-effective than a full box set.
What materials and classes are available for standard loose weights from Limra?
We supply loose weights in stainless steel and cast iron, across OIML classes from F1/F2 down to M1/M2, covering 1 gram up to 20 kg and beyond. Stainless steel suits lab and hygiene-sensitive use; cast iron is practical and economical for platform and floor scale calibration.
Can I buy a single loose weight like a 5 kg or 10 kg for platform scale calibration?
Yes, this is one of our most common requests from small factories and workshops. We supply individual loose weights in 1 kg, 2 kg, 5 kg, 10 kg, and 20 kg denominations sold singly. Tell us your scale's capacity and the calibration point you need, and we'll recommend the right weight and class.
Are Limra standard loose weights supplied with calibration certificates?
Yes, with certificates traceable to national measurement standards whether for a single weight or a collection. For ISO-certified facilities or audited companies, this documentation matters. Mention your certificate requirement when ordering.
How do I care for and store standard loose weights to maintain their accuracy?
Store in a clean, dry place away from moisture, vibration, and magnetic fields. For F class and above, use clean cotton gloves even fingerprints can measurably affect small denominations. For M class and cast iron weights, protect from knocks that could chip or deform edges, and recalibrate annually for most industrial use.
