Digital magnetic spirit level made of aluminum – backlit display, audible alarm and automatic display, waterproof to IP54

【Digital Protractor with Inclinometer】Measuring range: 4 x 90° (0–360°) for displaying angle and inclination values in degrees, slope in inches/feet, mm/m, and percentage inclination. The high-precision digital protractor can measure or set angles: Accuracy is ±0.1° at 0° and 90°; ±0.2° at other angles. Resolution: 0.05°.

【Audible Alarm and HOLD Function】This protractor has a built-in buzzer that sounds at 0° or 90°. The buzzer frequency increases as you get closer to 0° or 90°, until a constant tone sounds precisely at 0° or 90°. A unique data hold function allows for easy saving of measurements. The automatic reversal display in the protractor housing allows for easy reading of inclinations, even when the instrument is upside down. [V-Groove Base and Backlit Display] The V-groove base and strong magnets securely attach to curved or cylindrical magnetic surfaces (such as metal pipes or shafts) without any risk of loosening. The instrument stays firmly in place. The backlit LCD display allows for operation in low-light conditions and provides clearer readings. [Two Measurement Modes] The electronic spirit level features both absolute and relative measurement modes. Simply pressing the "ZERO" button allows you to switch between relative and absolute measurements in any position and quickly measure the angle between the two surfaces. The measuring device can also be used as an inclinometer, protractor, spirit level, and goniometer. [Aluminum Frame & IP65 Waterproof] Robust and durable aluminum frame, compact and lightweight, with a carrying case for easy transport and use; dustproof and waterproof according to protection class IP65, it is suitable for any workshop, e.g., woodworking shops, garages, or garden sheds. It is powered by 2 AAA batteries (not included), automatically shuts off after 3 minutes of inactivity, and has a battery level indicator.
