  • High accuracy computerised electronic mass comparators.

Capabilities

List of instruments calibrated by NML:


Mass standards & standard weights from 1mg up to 1000kg (metric and imperial) OIML Class E2, F1, F2, M1, M2 and M3

Masses cleaned and adjusted where necessary. Refurbishment service available for cast iron weights.
 
Measurement Range Best Measurement Uncertainty (sample)
OIML Class E2 1mg – 20kg 1/5th of OIML tolerance
OIML Class F1 & F2 1mg – 50kg 1/5th of OIML tolerance
OIML Class M1 1mg – 1000kg 1/5th of OIML tolerance
OIML Class M2 100mg – 1000kg 1/5th of OIML tolerance
OIML Class M3 1g – 1000kg 1/5th of OIML tolerance
