万能工具显微镜是机械行业使用最为广泛的一种测量仪器。按其凑数方式区分,它已经厉了目视、投影和数显三个阶段。山于数显读数采用高精度的光栅传感器,所以仪器的测量精度得到提高。随着微电子与微处理机技术的飞速发展,以及在精密光学仪器中的推广应用,产生了 Universal tool microscope is the most widely used machinery industry, a measuring instrument. According to the number of ways to make up the difference, it has been sharp visual, projection and digital display three stages. Mountain digital readout using high-precision grating sensor, so the instrument’s measurement accuracy is improved. With the rapid development of microelectronics and microprocessor technology, and the popularization and application of precision optical instruments,
