Spi MS150825008 Micrometer Calibration Standard 3 Inch

Product Description

The SPI MS150825008 is a precision micrometer calibration standard designed to verify and set the accuracy of screw thread micrometers. Measuring 3 inches in length, this calibration standard delivers accuracy up to 0.0001 inch (0.003 mm), making it a reliable reference tool for metrology applications in machining, manufacturing, and precision measurement environments. It arrives pre-calibrated from the factory and includes a heat insulating handle to prevent thermal expansion from hand contact during use. Licensed metrologists, machinists, and quality control technicians use this standard to maintain instrument traceability and measurement integrity on the shop floor or in a calibration lab.

This calibration standard is intended for use with SPI screw thread micrometers in settings where precise thread measurement verification is required. Typical applications include incoming inspection, in-process quality checks, and periodic instrument calibration in precision machining shops, toolrooms, and manufacturing facilities. The heat insulating handle makes it practical for repeated handling during calibration routines without introducing measurement error from temperature variation.

Key Features

• Accuracy up to 0.0001 inch (0.003 mm) for high-precision calibration reference
• 3-inch length suitable for setting screw thread micrometers in that range
• Pre-calibrated from the manufacturer for immediate use out of the box
• Includes heat insulating handle to minimize thermal expansion during handling
• Designed specifically for use with SPI screw thread micrometers

Compatibility

Designed for use with SPI screw thread micrometers. Consult your instrument documentation to confirm this standard matches the measurement range and thread form of your specific micrometer model.

Installation Notes

Calibration standards should be handled by qualified metrologists or trained technicians following established metrology procedures. Allow the standard to thermally stabilize to ambient lab temperature before use to ensure accurate reference readings. Always clean contact surfaces with a lint-free cloth before use and store the standard in its protective case when not in service to prevent damage to the reference surfaces.
