NIST-Traceable Dimensional Metrology Station
Full dimensional metrology station with NIST-traceable reference standards. Mitutoyo reference artifact set anchors the traceability chain. Three independent gage block sets for cross-verification — no single instrument error goes undetected. Vermont pin gage library covering .061"–.500" — both ranges in Class ZZ Plus. Shars blade mic, Fowler/SPI calipers, granite surface plate, and digital height gage.
