8" x 8" Precision Frame Spirit Level Specification: Material: Cast Iron Accuracy: 0.0002"/10" Size: 8" x 8" (Square Structure) Usage: Precision frame spirit levell is mainly used to test the flatness of various machine tools and other equipment guide rails, according to the accuracy of the horizontal position and vertical position of the installation, and can test the small dip Angle Applicability: For some equipment, the level requirements are guaranteed by verticality, such as column processing or vertical processing surface equipment, the level of this equipment needs to be measured with a frame level. Note: When measuring, make the working face of the level close to the measured surface, and read after the bubble is completely stationary In order to avoid the measurement error caused by the inaccurate zero position of the level, the zero position of the level must be proofread or adjusted before use
