Digital Angle Indicators with Calibration Certificate
These angle indicators come with a calibration certificate that's traceable to NIST and includes the test measurements that confirm accuracy. The display shows highly accurate angle, level, and tilt measurements. They come set at true 0°, but you can choose an alternate zero point with the push of a button. Another button will freeze the reading on the display. Indicators have machined leveling surfaces, a V-groove for stability on curved surfaces, and two 6-32 threaded holes for mounting.
Angle indicator with an RS-232C computer connection can be used for ASCII output.

Certified Mitutoyo Precision Protractors
With a calibration certificate traceable to NIST that says they’ve passed a test for accuracy, you can trust these protractors to measure angles on molds and jigs precisely. They have angle graduations from 0° to 90° in four quadrants. Also known as bevel protractors, they have an adjustable arm. These protractors are satin chrome-plated to resist corrosion and reduce glare. Their etched markings are wear resistant.

Calibration Squares
Check the tool path of your CNC machine with the highest degree of precision. These calibration squares can lay flat to check that the X- and Y-axes of your tool path are at 90°. Or sit them up vertically to confirm the Z-axis is perpendicular. Made of Laboratory Grade AA granite, these squares have the tightest flatness tolerance available for granite. They also come with a calibration certificate traceable to NIST that states they've passed a test for accuracy. Moisture, coolant, and chips won't affect the granite, so they remain accurate even when used inside a milling machine. You can also use them to check the squareness and parallelism of finished workpieces.
They have drilled holes to reduce their weight and make them easy to position.
Tri-square plates have a face and two edges for checking 3-axis machines.
Square plates have two additional edges for checking both 3-axis and 5-axis machines.
