High Precision Solid Aluminum Level Measuring Instruments Anti-drop Strong Magnetic Bubble Level Balancer Ruler Measuring Tools

The main function of the folding ruler is to measure the size and shape of geometric figures. It can be used to measure length, width, thickness, outer diameter and other dimensional parameters. When measuring, you can place the folding ruler on the object to be measured and use the small pulley of the measuring ruler to rotate a certain angle to measure. The angle of rotation of the pulley and the number of scales on the measuring ruler can be used to calculate the measurement result. In addition, the folding ruler can also measure other dimensions, such as angles, circumference, etc. Product name: Solid aluminum level Product dimensions (without packaging) :400mm×50mm×24mm Material: Solid aluminum +ABS plastic Measurement accuracy (blister) 0.5mm/m in the middle, 1mm/m on both sides Number of magnets: 3 Number of measuring surfaces: 1
