Calibration Services


MicrometerWhile checking zero is an important step that should be done daily by the operator, a full calibration is much more than that. Your hand tools will be cleaned, checked for correct operation on every feature, and calibrated throughout the entire operating range. ATRONA calibrates all types of hand tools - from calipers and various dial gages to micrometers and tape measures.

Whether internal or external, plain or threaded, or a general inspection gage, we are able to provide a complete inspection report for your fixed attribute gages. Plugs and rings will be sealed with a protective wax coating to both preserve your gage and to indicate if the gage has been used, reducing your calibration costs. ATRONA calibrates a full range of hard gages, including: 1-2-3 Blocks, Caliper Checkers, Feeler Gages, Kalmasters, Length Standards, Micrometer Masters, Parallels, Pin Gage Sets, Plug and Ring Gages, Steel Rules and Straight Edges, Thickness Gages, V Blocks, and more.
