PHASE II SPG-1000 Digital Surface Profile Gauge

The SPG-1000 Digital Surface Profiler can accurately measure the peak-to-valley height of the blasted surface. The initial setting of the surface profiler is the zero calibration piece, which is then placed on the blast profile with a press-foot. The foot presser is placed at the top of the peak, and the sharp stylus moves to the valley floor so that the surface profiler shows the height of the peak-valley. Multiple measurements can be taken and then an average value is obtained. 
The PHASE II brand surface profiler SPG-1000 comes standard with a glass zero calibration sheet, operating manual, calibration certificate, battery and instrument case

The PHASE II SRG-2000 comes standard with a main unit, a standard calibration template, a charger, an operating manual and an instrument case.

A guide to surface roughness meter measurements 

The purpose of surface roughness is the result of some machining processes and their action on the surface of the material involved. 
The sliding surface roughness gauge is a common instrument in the workshop. The diamond stylus glides over the sample block and the piezoelectric sensor records the vertical movement. The recorded peaks and troughs are converted into established parameter values. 
The roughness parameter varies depending on how the peak and trough values are reached. When measuring roughness, the commonly used parameter is "Ra", which is often defined as the arithmetic mean roughness. The Ra parameter is an easy-to-use, valid parameter, and there are many other parameters that are more specific and effective depending on the application requirements. It is with these parameters that we are able to define the surface roughness.
Now, in order to detect Ra parameter values, a portable hand-held surface roughness Tester is used, which is not only inexpensive and economical, but also digitally displayed and easy to operate. The surface roughness Tester is a required instrument for those factories that have Ra value testing requirements.
