JSN-1A Mechanical comparatorDetailed product description：

JSN-1A mechanical comparator

Model: JSN-1A
Mechanical comparator
Product Introduction
Mechanical comparator is suitable for measuring the geometric dimensions and positional deviations of workpieces, especially for verifying the runout of workpieces, and can be used to measure length by comparison method. The comparator calibration bench is a calibration platform used for mechanical comparators, which can be used in conjunction with measuring blocks to measure performance indicators such as the variability of the comparator's readings. At the same time, the comparative method is used to measure the length change of Gongjuan, which is only used for precise measurement.
