1.Relative /absolute measurements interchcange at any position 2.Angle and slope readout conversion 3.Data hold 4.The display will be turn off if you don't operate the device within 30 seconds ,the dispaly will automatic turn off if you don't operate it within 3 minutes 5.Compact and portable ,wide application 6.Four side built-in powerful magnets 7.Rechargeable battery Application It is widely applied in wood processing industry (especially in furniture manufacturing dustry) for the accurate cutting of wood angle ;auto repair industry for the accurate control of tire angle ;maching industry for the accurate position of tool working angle as well as the roation angle of large vehicle arm etc Size: 6.1*6.1*3.1 cm / 2.4*2.4*1.22 inches Precise measurement, diverse functions: As a dual-side light four-sided magnetic digital inclinometer, it can achieve various functions such as angle measurement, slope measurement, and relative measurement, meeting the precise measurement requirements for different scenarios. The measurement range is up to 4×90° (i.e., 360 degrees in all directions), with a resolution of up to 0.05°, an accuracy of 0.2 - 0.5°, and a repeatability of 0.1°, providing reliable guarantees for measurement results. Magnetic suction design, convenient fixation: The four corners of the instrument are equipped with strong magnets, which can stably attach to any metal object, freeing hands and making the measurement process more convenient and efficient, especially suitable for various complex industrial environments. Dual-side light assistance, intuitive operation: The dual-side light ray design is a major highlight. By short-pressing the power button, the left light can be turned on. When both lights are on, they can provide a clear reference line, helping users measure and align more intuitively, improving the accuracy and convenience of measurement. Data locking and backlight function: It has a data locking function, which can ensure that the measured data remains stable during recording or viewing, avoiding data loss or changes due to incorrect operation. At the same time, the LED backlight function allows the instrument to clearly display the measured data in dim environments, facilitating users' use in various working conditions. Wide applicability: It reaches IP54 protection level, unaffected by dust during normal use, and suitable for various harsh working environments. It is widely used in woodworking, equipment level installation, automotive maintenance, mechanical processing, railway construction, decoration and renovation, construction, and instrument testing, among other fields.
