Product type
A gauge block set consists of a collection of precision ground blocks made from high-quality materials such as steel or ceramic. These blocks are used as reference standards for measuring length and calibrating measuring instruments. The blocks are available in various thicknesses and are often used in conjunction with micrometers, calipers, and other measuring tools to ensure accuracy in measurements.
| Material | Steel, ceramic, or carbide |
| Tolerance | Typically ±0.001 mm to ±0.01 mm |
| Standard sizes | Commonly from 1 mm to 100 mm |
| Set configurations | Available in sets of 5, 10, 20, or more blocks |
| Calibration certification | Usually provided with NIST or ISO certification |
When selecting a gauge block set, consider the material and the level of precision required for your applications. It's important to specify the tolerances and any necessary certifications, such as NIST or ISO, to ensure compliance with industry standards. Additionally, think about the quantity needed and whether a complete set or individual blocks would best suit your needs.

Gauge blocks are used for precise measurements and calibration of measuring instruments.
They are calibrated using precision measurement techniques and are often certified by standards organizations.
Common materials include steel, ceramic, and carbide, each offering different benefits.
Typical tolerances range from ±0.001 mm to ±0.01 mm depending on the grade.
Some gauge blocks are designed for high-temperature applications, but standard blocks may not perform well in extreme conditions.
They should be stored in a protective case to prevent damage and contamination.
