eOUTIL Digital Protractor Inclinometer Angle Finder with Magnetic Base, 0.1° Accuracy, Black | Precision Bevel for Woodworking & Construction

• V-groove Magnetic Base: This magnetic V-groove base of digital angle gauge can be firmly attach to ferrous metal surfaces like pipe, steel construction framing, metal fabrication. Rugged durable aluminum frame for precision leveling measurement
• Absolute & Relative Measurement: This digital protractor has absolute angle measurement to test whether the working surface is on the level to check roof slopes, wheel alignment, etc. Moreover, this magnetic level lets you check the relative angles between the surfaces
• High Accuracy: Accurate to the ±0.1° at 0° and 90°; ±0.2° at other angles. Displays angle and bevel readings in degrees, pitch IN/FT, mm/M, and percent slope. With reading hold function, it is convenient to record by this level digital inclinometer bevel box. Moreover, you can have an accurate measurement of the angles between two
• Backlight LCD Display With Audio Indicator: Featuring a large, bright LCD display you can easily read the measurements whatever the light conditions. The display value reverses automatically when the electronic level is upside down. Acoustic signal routing via beeps when you reached 0° or 90°
• IP65 Waterproof And Dust-proof Level: It has IP65 protection which makes it suitable for use in harsh environmental conditions. The inclinometer battery cover and other high-sealing truction design make sure its good working in an environment with splashing water and dust

• Install Batteries — Open the battery cover and insert 2x AAA alkaline batteries, ensuring correct polarity. Close the cover securely. The device requires batteries for operation.
• Select Measurement Mode — Press the 'ABS/REL' button to switch between absolute angle measurement (relative to gravity) and relative angle measurement (between two surfaces). Choose the mode appropriate for your task.
• Take Measurement & Read Display — Place the magnetic base on a ferrous surface or hold the tool against your workpiece. The angle will display on the backlit LCD. Use the 'HOLD' button to freeze the reading. The display reverses automatically when upside down.
• Change Units & Use Audio Cues — Press the 'UNIT' button to cycle through display units (degrees, in/ft, mm/m, % slope). Listen for the audible beeps that indicate when you have reached precisely 0° or 90°.
