The INSIZE 2172‑360A Digital Protractor is a precision instrument designed for angular measurement across the full 360° range. It supports both degree display and degree/minute/second format. A SET button allows presetting the reading or changing measurement direction, and a MODE button lets you select among 0–90°, 0–180°, or full 0–360° display modes.
It comes with two blade lengths (300 mm and 150 mm) and a square for 90° setup. A fine adjustment mechanism aids in precise alignment. The unit also supports data output via optional cable, zero memory (no need to reset when changing battery), and auto shut-off. It’s built from stainless steel for durability in shop conditions.
This tool is ideal for machinists, toolmakers, and inspectors needing accurate angular measurements in jigs, setups, λ fixtures, and more.
