Magnetic digital inclinometer made of aluminum with acoustic alarm, automatic display, digital protractor, backlit display and IP54 water protection.

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

【Audible Alarm and Memory Function】This protractor has a built-in buzzer that emits an audible signal at 0° or 90°. The signal frequency increases as you approach 0° or 90°, reaching a constant tone precisely at 0° or 90°. A unique data memory function allows for easy saving of your measurements. The self-reversing display on the protractor housing allows for easy reading of inclinations, even when the instrument is upside down. [V-Groove Base & Backlit Display] The V-groove base with strong magnets adheres securely to curved or cylindrical magnetic surfaces (e.g., metal pipes or shafts) without the instrument detaching. The backlit LCD display facilitates working in the dark and provides a clearer representation of measurements. [Two Measurement Modes] The electronic level features both absolute and relative angle 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 two surfaces. The calibration tool can also be used as an inclinometer, protractor, spirit level, and angle finder. [Aluminum Frame & IP65 Protection] The robust and stable aluminum frame, compact and lightweight design, and included carrying case facilitate transport and use. Thanks to its IP65 rating, the device is dustproof and waterproof, making it suitable for use in any woodworking shop, garage, or garden shed. The device is powered by two AAA batteries (not included), automatically switches off after three minutes of inactivity, and displays a low battery warning.
