 Why F1 Class?

Because regular weights cause:

❌ Calibration drift
❌ Balance instability
❌ Failed audits and measurement errors

F1 Class provides:

✔ Tighter tolerances than F2/M1/M2 classes
✔ Perfect for high-resolution (0.001g – 0.01g) balances
✔ Traceability to national/international standards
