Insize Micrometer Accessories
Supplied with a pair of 5mm carbide gage blocks, ISO3650 grade 0.
Johansson gauge blocks (jo blocks) are length standards used in metrology and quality control to provide a highly accurate reference for machine setup, dimensional verification and calibration of measuring instruments. Their exceptional flatness and “wringing” capability deliver repeatable, traceable measurements.
Available as sets with different step progressions and accuracy grades, in steel or ceramic, supplied in protective cases and with certificates/traceability options where required, from Insize. Choose based on metric/imperial standard, grade and the working environment.
Commonly used in calibration labs, machine shops and production lines for checking calipers, micrometers and dial indicators.
Johansson Tiles
The Johansson gauge blocks, also known as gauge blocks, are the global reference for linear measurement in machining. They are blocks made of steel, ceramic, or tungsten with surfaces machined with such precision that the phenomenon of wringing (wringing) between them is achieved to create composite dimensions.
- Accuracy: Available in grades (Grade 0, 1, 2), with Grade K used as a calibration standard for other instruments.
- Applications: Used for setting micrometers, checking measuring instruments, and as fixed standards in precision engineering.
- Features: Distinguished by their excellent dimensional stability and low surface roughness, ensuring micrometer-level ($\mu m$) measurements.
