Capability
Mass & Balance Calibration
A dedicated mass lab held to ±0.5 °C, because Class 1 demands it.
Mass calibration runs in its own environmentally isolated laboratory on four Mettler mass comparators driven by MCLink software. The room holds ±0.5 °C and ±5 %RH during calibration, with each comparator’s weighing cavity independently monitored. We are accredited for ASTM and OIML Class 1 weights up to 25 kg.
