- V-Groove Magnetic Base: Securely attach this digital angle gauge to ferrous metal surfaces, including pipes, steel frames, and metal fabrication. The durable aluminum frame ensures precision in leveling measurements. - Absolute and Relative Measurement: This digital protractor allows you to check if surfaces are level for applications such as roofing and wheel alignment. It also facilitates the measurement of relative angles between different surfaces. - High Accuracy: Achieve precise readings with an accuracy of ±0.1° at 0° and 90°, and ±0.2° at other angles. The display shows angles in degrees, pitch IN/FT, mm/M, and percent slope. The reading hold function allows for easy recording of measurements, making it ideal for determining angles between two surfaces. - Backlight LCD Display with Audio Indicator: The large, illuminated LCD screen ensures visibility in any lighting condition. The display automatically reverses when the unit is turned upside down. An audio indicator confirms when measurements reach 0° or 90°, enhancing user experience. Applications include HVAC installation, carpentry, and metalworking. This digital angle gauge is a valuable tool for professionals seeking reliable, accurate measurements in various settings. The combination of robust construction and advanced functionality makes it an essential instrument for achieving precise angles.
