Description

The Digital Protractor is a revolutionary measuring tool to build 0.1 degree accuracy at vertical and horizontal planes and 0.2 degrees accuracy at other angles. The machined stainless steel frame with integral base-plate is a light, rigid and ultra-precise platform allowing the state-of the-art sensor and microprocessor circuit to provide unsurpassed accuracy throughout the protractor` s **0degrees range. The front panel buttons can be used to capture desired readings or to designate an alternate reference surface from which subsequent angles are then measured. The unit can also be easily recalibrated in any available flat surface. The unit is usefulness in angle finder, measure bevel and square angle and widely applied in making, using, examining or repairing machines, vehicles, and tools, such as driving shaft alignment and wheel alignment, calibrating aircraft flap, installing precision machines, laying out road or rail-track and so on. Features: (1) Conversion between absolute measurement and Relative measurement. (2) Hold function to freeze measurements. (3) Automatic shut off after 5 minutes. (4) Three-in-one measuring tool—angle finder, protractor, level. (5) Easy to recalibrate without special tools. (6) Easy to read**- the content displayed on LCD will intelligently flips over when the unit is upside down. (7) Could take any angle as 0 degree. Specifications: (1) Resolution: 0.1 degree. (2)Accuracy: 0~*0 degree ≤0.1 degree; the rest degree≤0.2 degree. (3) Measuring range:4×*0degree (0~**0degree) degree (0 ~**0 degree) . (4) Working current : <**0uA. (5) Work temperature : *5 oC~**0 oC (6) Working humidity: ≤*5%RH. (7) Power: 3V CR***2 Lithium battery. (8) Battery life: More than ***0 hours.
