A check master (or gauge block check master) is a precision reference tool designed specifically for verifying
and calibrating the accuracy of various measuring instruments such as calipers, height gauges, micrometers, dial
indicators, and other dimensional measuring tools. By using a check master, you can ensure that your measurement
instruments are providing accurate and consistent readings over time, which is essential for maintaining quality
control in manufacturing, machining, and other industries.

A check master is a valuable tool for anyone involved in precision measurement, ensuring that their instruments
are accurate, reliable, and calibrated according to recognized standards.

Benefits of Using a Check Master:

• Ensures Accuracy: Regular checks with a check master
  help maintain the accuracy of measuring tools, reducing errors in production
  or inspection processes.


• Minimizes Downtime: Quick verification and calibration
  of tools using a check master help to avoid lengthy downtime due to faulty
  measurements or tool readjustment.


• Cost-Effective: By identifying out-of-tolerance
  measuring tools early, costly rework or scrapping of parts can be avoided.


• Easy to Use: The design of a check master allows for
  simple, quick checks without the need for extensive training or complex
  setups.
