Spi MS160712008 Micrometer Calibration Standard 8 in

Product Description

The SPI MS160712008 is a flat-end micrometer calibration standard designed to verify and maintain the accuracy of outside micrometers used in precision measurement applications. Measuring 8 inches in length with a calibrated accuracy of up to 0.0002 inches, this standard provides a reliable reference point for confirming micrometer zero settings and overall instrument performance. The unit ships pre-calibrated and includes a heat insulating handle to prevent thermal expansion from hand contact, which is a critical consideration when working at this level of measurement precision. It is suited for use in tool rooms, calibration labs, and production environments where measurement traceability is required.

This calibration standard is intended for use with outside micrometers across a range of professional settings including manufacturing, machining, and quality control environments. Technicians and metrologists use standards like this one to check micrometer anvil and spindle condition, confirm instrument calibration between scheduled lab intervals, and satisfy in-house quality assurance documentation requirements. The 8-inch length covers a measurement range appropriate for larger-capacity micrometers common in industrial trades.

Key Features

• Pre-calibrated accuracy up to 0.0002 inches for reliable micrometer verification
• Flat-end design compatible with standard outside micrometer anvil and spindle faces
• 8-inch length accommodates larger-range micrometer verification needs
• Includes heat insulating handle to minimize thermal growth during handling
• Calibrated at the factory for immediate use upon receipt

Compatibility

Designed for use with outside micrometers requiring an 8-inch flat-end calibration reference standard.

Installation Notes

This standard is handled and used by calibration technicians or quality control personnel, not installed in a system. Always allow the standard and the micrometer to reach the same ambient temperature before use to avoid measurement error from thermal expansion. Store the standard in its case when not in use to protect the reference surfaces from damage or contamination. Follow your facility calibration procedures and applicable metrology standards when performing instrument verification.
