Digital Protractors with Level and Laser
A dot laser extends the working distance 200 feet beyond the tool length. This tool has two digital displays that invert when turned upside down; one shows the base angle and the other shows the moveable arm angle. It also has a lock to hold the arm in position, a hold button that freezes the display, auto shutoff, and 1/4"-20 threads for connecting to a tripod.

Digital Angle Indicators
These angle indicators display 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-232 computer connection can be used for ASCII output.

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.

Digital Horizontal-Plane Angle Indicators
Check the angle of your horizontal surface side-to-side and front-to-back. These indicators have a highly accurate sensor and precision ground stainless steel base. The LCD display shows slope, level, and angle in numerical values along with an image of a manual angle indicator. If you flip them so the LCD display is upright, they’ll automatically switch from checking two angles to check a single angle on a horizontal or vertical surface. They come with cable and a wall plug adapter for charging.
Because it’s stainless steel, the base makes these indicators a durable choice for industrial applications where plastic-bodied indicators would be too fragile. Mount them to equipment, even if it’s vibrating, to repeatedly check angles. A V-groove provides stability on curved surfaces.
