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.
