Instrument Calibration Solutions (ICS), a Brechbuhler Scales company, provides ISO/IEC 17025 accredited dimensional calibration for gage blocks, ring gages, micrometers, calipers, indicators, thread and pin gages and more. Calibrations are traceable to NIST and are performed in our Clayton, OH and Aliquippa, PA laboratories or by our mobile calibration lab based in Canton, OH, which comes to your facility.
Every ICS lab, including the mobile lab, can perform all of the dimensional calibrations listed below.
Our dimensional calibration equipment
ICS's workhorse is a Pratt & Whitney Labmaster Universal 1000A automated ID/OD/SD gage calibration and part measuring system with a 40 inch (1016 mm) direct reading range. We also offer non-contact measuring solutions.
Our systems are in a temperature-controlled lab with humidity maintained at 45% relative humidity. Temperature control matters because steel expands about 11.5 micrometers per meter for every degree Celsius, so a 100 mm steel gage block grows more than a micrometer per degree.
All items are cleaned and inspected upon entry to the lab using the highest quality cleaning materials and an ultrasonic cleaner as necessary.
ICS is a Brechbuhler Scales company, so your calibration is backed by the local branch support you already know.

Dimensional calibration FAQs
How often should micrometers, calipers and gage blocks be calibrated?
Intervals depend on how often a tool is used, how much it wears and how critical the measurement is. Many shops calibrate micrometers, calipers and indicators every 12 months, and set longer intervals for well-kept reference gage blocks based on their calibration history. Your quality system sets the final interval.
Why does the lab temperature matter for dimensional calibration?
Steel expands about 11.5 micrometers per meter for every degree Celsius. A 100 mm steel gage block changes by more than a micrometer for each degree of temperature difference, which is why our dimensional work is done in a temperature-controlled lab with humidity maintained at 45% relative humidity.
What is the longest length you can calibrate?
Our Pratt & Whitney Labmaster Universal 1000A has a 40 inch (1016 mm) direct reading range, and we calibrate end measuring rods up to 40 inches.
Do you calibrate thread plug gages, including NPT?
Yes. Our capabilities include thread plug gages, including NPT, along with ring gages, pin gages, depth gages and height gages.
Why are gages cleaned before calibration?
Dirt, oil and residue on a gage can change what it measures. Every item is cleaned and inspected when it enters our lab, using an ultrasonic cleaner as necessary, before any measurements are taken.
Can you calibrate on-site?
Yes. Our mobile calibration lab, based in Canton, OH, comes to your facility and can perform all of the dimensional calibrations listed above. You can also send instruments to our Clayton, OH or Aliquippa, PA laboratory.
What does ISO/IEC 17025 accreditation mean for my audit?
ANAB accreditation means an independent body has assessed the laboratory's technical competence, equipment and measurement uncertainty. ISO 9001, AS9100 and IATF 16949 audits expect calibration that is traceable to national standards, and accredited calibration is the most direct way to show it. The ICS accreditation certificate is linked at the top of this page.
Do you offer non-contact measuring?
Yes. We offer non-contact measuring solutions in addition to contact gage calibration.
