Description
The MITUTOYO 295-153 is a spherical face micrometer designed for precision dimensional measurement in manufacturing, machining, and quality control environments. It measures from 0 to 1 inch with a resolution of 0.00005 inches and an accuracy of 0.00015 inches, making it suitable for high-tolerance inspection work. The ball-type anvil contacts curved or irregular surfaces cleanly, and the ratchet stop thimble ensures consistent measuring force on every use. A satin chrome finish reduces glare and resists corrosion. This instrument is used by machinists, metrologists, and quality technicians who require reliable, repeatable measurements in demanding shop environments.
The 295-153 is built for precision measurement applications where a standard flat-anvil micrometer cannot make reliable contact. The ball anvil design is particularly effective when measuring the wall thickness of tubing, curved workpieces, or features that require a point contact. It operates mechanically with no digital display, relying on a traditional thimble-and-barrel scale graduated at 0.0001 inch increments. It ships with a plastic storage case and one SR44 battery. The instrument carries a TUV certification and is rated IP65 for protection against dust and water ingress, making it usable in wet or contaminated shop environments.
Key Features
- Ball-type anvil for accurate contact on curved and irregular surfaces
- Ratchet stop thimble for consistent, repeatable measuring force
- Resolution of 0.00005 inches with 0.0001 inch graduation scale
- IP65-rated for dust and water resistance in shop environments
- Satin chrome finish reduces glare and improves corrosion resistance
- TUV certified; includes plastic storage case and SR44 battery
Compatibility
Designed as an OEM-style precision measuring instrument suitable for general metrology and quality control applications where a spherical anvil micrometer in the 0 to 1 inch range is required.
Installation Notes
This instrument requires no installation. Before use, clean the measuring faces and verify the zero setting against a calibrated standard. Store in the included plastic case when not in use to protect the measuring surfaces. Calibration should be performed by a qualified metrologist at intervals appropriate to your shop quality management system.
