Mitutoyo 345-350-30 Electronic Inside Micrometer

Product Description

The MITUTOYO 345-350-30 is an electronic inside micrometer designed to measure internal dimensions with high precision. It covers a measurement range of 0.2000 to 1.1800 inches and delivers a resolution of 0.00005 inches, making it well suited for tight-tolerance bore and hole inspection work. The instrument features a two-contact-point design and includes data output capability, allowing readings to be logged to a compatible data collection system. Licensed machinists, metrology technicians, and quality control professionals rely on this type of instrument for precise internal measurement in production and inspection environments.

This inside micrometer is used in machine shops, manufacturing facilities, and inspection labs where accurate bore diameter verification is required. It is appropriate for both small production runs and high-volume quality control operations. The data output function supports statistical process control workflows by connecting to SPC software or data loggers. The included plastic case keeps the instrument protected during storage and transport between workstations or job sites.
