Product Description

The AngleStar® DP-45 Digital Protractor is a handheld, portable angle measurement instrument. Consisting of a rugged electronic sensor, custom circuitry and liquid crystal display, this easy-to-use device provides instant digital display of the angle, eliminating the interpretation errors associated with bubble levels and mechanical protractors. The frame of the DP-45 is made from a high impact plastic with a 'V' groove profile, making it ideal for measuring both flat and curved surfaces. The 'Alternate Reference' function allows the DP-45 to be 'zeroed' at any angle within the measurement range, enabling the measurement of compound angles. Other features include display hold, low battery warning and over-range indication.

Also see our other models, AngleStar Protractor System® (APS) (handheld digital protractor), AccuStar® Electronic Clinometer (4 standard input/output configurations), and AccuStar® IP-66 (2-wire loop powered angle transmitter).
