Solala Angle Gauge eOUTIL Digital Protractor Inclinometer Angle Finder with V-Groove Magnetic Base Tape Measure  (20 cm)

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
