Spi CMS220519059 Electronic Inside Micrometer 87-100mm

Product Description

The SPI CMS220519059 is an electronic inside micrometer designed for precision internal bore measurement across a range of 87.00 to 100.00 mm. It features solid carbide measuring faces for durability and wear resistance, a ratchet stop thimble for consistent measuring pressure, and data output capability for integration with statistical process control or digital readout systems. The instrument is factory calibrated and arrives ready for use with a lithium CR2032 battery included. This micrometer is suited for quality control technicians, machinists, and metrology professionals requiring repeatable, high-accuracy internal measurements in production or inspection environments.

This inside micrometer is used in industrial and manufacturing settings where tight-tolerance internal diameter verification is required. The extension rod design allows measurement within bores, cylinders, and housings where calipers or bore gauges lack the precision or reach. A gage depth of 114.00 mm and a maximum extension rod length of 6 inches make it applicable across a range of workpiece configurations. It is appropriate for both shop-floor use and dedicated inspection rooms.

Key Features

• Measurement range: 87.00 to 100.00 mm for precise internal bore measurement
• Accuracy of plus or minus 0.00020 inches for high-tolerance inspection work
• Solid carbide measuring faces resist wear during repeated use
• Ratchet stop thimble ensures consistent, repeatable measuring pressure
• Data output port supports SPC integration and digital recordkeeping
• Factory calibrated and includes a 3V CR2032 lithium battery

Compatibility

Designed as a precision bore measurement tool suitable for use wherever internal micrometer measurement in the 87.00 to 100.00 mm range is required. A setting ring with a 3.5000 decimal inch diameter is specified for calibration reference.

Installation Notes

This instrument is set up and operated by qualified machinists or metrology technicians following established shop or laboratory procedures. Before use, verify calibration with the appropriate setting ring and ensure the measuring faces are clean and free of debris. Handle carbide measuring faces with care to prevent chipping or damage that would affect accuracy. Store in the provided case when not in use to protect the electronic components and measuring surfaces.
