Features: With 4 x 90 measuring range and 0.2 high accuracy, the two-sided laser digital inclinometer is designed for measure the tilt angle quickly and accurately. Relative/ absolute measurement interchange at any position; the absolute zero position has been factory-calibrated, the relative zero position can be set at any slope. 1.8-inch digital LCD screen, angle and slope readout conversion, data hold function, clear and intuitive. 3 minutes automatic shutdown function to save energy. 300mAh rechargeable lithium battery ensures strong endurance; quickly recharge it via the type-C USB charging port. Built-in magnets in 4 corners ensure the inclinometer and measured object are close fitting. Mini size, lightweight and portable. Widely used in wood processing industry (especially in furniture manufacturing) for the accurate cutting of wood angle, auto repair industry for the accurate control of tire angle, machine industry for the accurate position of tool working angle as well as the rotation angle of large vehicle arms, and etc. Note: Size and color may be slightly different due to manual measurement and different light conditions.
