OIML Standard Weights Box Class F1-F2

Reliable Calibration Standards for Laboratory & Industrial Use

Accurate measurement begins with accurate reference standards. Limra Instruments manufactures high-quality OIML Standard Weights Boxes - Class F1 and Class F2 in India, designed for dependable calibration of precision balances and industrial weighing equipment.
Our F1 and F2 weight sets are engineered to provide stable mass values, consistent performance, and long-term reliability for laboratories, production facilities, and calibration service providers.

Understanding OIML Class F1 & F2 :

The OIML (International Organization of Legal Metrology) classification defines tolerance limits for calibration weights based on accuracy requirements.

• Class F1 :
  Used for calibrating high-precision balances and for verification of M1 class weights.
  Offers tight tolerance limits suitable for laboratory-grade applications
• Class F2 :
  Designed for calibration of medium-precision balances and for industrial weighing verification.
  Ideal for routine calibration tasks where consistent performance is essential.

Limra Instruments manufactures both classes following controlled machining and verification processes.
