Calibration

As further commitment to the quality of our products and services to our customers, Dorsey Metrology Calibration Laboratory was formed in 2010. The laboratory was accredited by A2LA on October 14, 2010 to ISO 17025 General Requirements for the Competence of Testing and Calibration. Having this accreditation has allowed Dorsey to remain highly competitive in the ever-changing manufacturing sector and encourages even further confidence in the quality of our products.

We are fully equipped to calibrate the full line of Dorsey and Standard Gage products. We offer ISO 17025 Accredited Calibrations (see our Scope of Accreditation for details) as well as Long Form Certifications.

Our calibration laboratory has an independent environmental system that controls temperature and humidity. Ultra precision equipment allows us to attain length measurement values to .0000010" (one millionth of an inch). All primary standards are traceable to N.I.S.T. or similarly recognized bodies. Equipment as follows:

• 16" optical comparator, .0001" resolution, 10-100x magnification.
• Multi-function digital laser interferometer universal measurement system (UMS) for length measurement of up to 48" with .000001" resolution.
• Multi-function vertical column electronic height gage for measurements up to 28" with .00001" resolution.
• Miscellaneous layout equipment.
• Specifically designated to calibrate short-range dial indicators to .00002" resolution.
