 Overview: 
 GH430 surface roughness measuring instrument is suitable for the measurement needs in production environments and mobile handheld instruments, it is easy to operate, full-featured, quick measurement, accuracy and stability, easy to carry, capable of measuring the main parameters of the latest international standards, the instrument fully strict implementation of international standards. The instrument can be connected to the printer and computer. 
 Measuring principle: 
 This instrument in measuring the surface roughness, the first sensor to take on the workpiece surface to be measured, and then start the instrument constant velocity straight-line glide along the surface to be measured from inside the instrument's precision drive mechanism driven sensor, sensor built-in sharp stylus feelings of the measured surface roughness, the roughness of the workpiece surface to be measured will cause the stylus displacement, the displacement sensor inductance coil inductance changes, which in the phase sensitive detector output the measured surface roughness is proportional to the analog signal, the signal after amplification and the level after conversion into the data acquisition system, the DSP chip on the data collected by digital filtering and parameter calculation, the measurement results are given on the LCD display, can also be output on the printer, you can also communicate with the PC
