Mitutoyo 950-318 Digital Protractor 360 Degree

Product Description

The MITUTOYO 950-318 is a digital protractor designed for precise angle measurement across a full 360-degree range. It operates on a single 9-volt battery rated for up to 500 hours of continuous use, making it a reliable tool for extended fieldwork and shop use. Accuracy is rated at 0.05 degrees from 0 to 10 degrees, 0.10 degrees from 80 to 90 degrees, and 0.20 degrees from 10 to 80 degrees. The unit includes a data output port, supporting integration with SPC data collection systems. Electricians, HVAC technicians, plumbers, pipefitters, and sheet metal workers use this instrument for layout, fabrication, and installation tasks requiring verified angle measurements.

The 950-318 is suited for both shop and field environments where angular verification is required. Typical applications include ductwork layout, pipe fitting alignment, structural framing checks, and equipment leveling. The digital readout eliminates interpretation error common with analog protractors, and the 360-degree range covers acute, obtuse, and reflex angles in a single setup. It ships with a plastic carrying case for storage and transport. No magnetic base is included with this unit.

Installation Notes

No installation is required for this instrument. Calibration verification against a known reference angle is recommended before use in critical layout applications. Keep the instrument dry and free from metal shavings or debris that could affect the pivot joint or readout. Battery replacement requires a standard 9-volt battery and a small screwdriver to access the battery compartment.
