    Image of Attribute. Front orientation. Angle Indicators. 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.
    RS-232—Angle indicator with an RS-232 computer connection can be used for ASCII output.

    Mitutoyo Precision Protractors with Calibration Certificate

    Image of Product. Front orientation. Protractors. Mitutoyo, Precision.
    Precisely measure angles on molds and jigs. This protractor has angle graduations from 0° to 90° in four quadrants. Also known as a bevel protractor, it has an adjustable arm. Protractor has a corrosion-resistant satin chrome-plated finish that reduces glare and wear-resistant etched markings. To measure angles from 0° to 90°, add an acute-angle attachment.
    Calibration Certificate Traceable to NIST—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.

    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-Squares—Tri-square plates have a face and two edges for checking 3-axis machines.
    Squares—Square plates have two additional edges for checking both 3-axis and 5-axis machines.
