PHASE II company introduces a new model of Specialized Technology Surface Roughness Tester SRG-4500, which adheres to the highest level of quality control in production, workshop and laboratory. The extended storage and output capabilities, combined with a wide range of useful features, make the SRG-4500 an obvious participant in ultra-accurate surface profile testing.
This kind of surface roughness Tester is distinguished from other brand products by high precision, more measurement parameters and simple operation. The PHASE II Surface Roughness Tester provides 15 popular surface roughness parameters including Ra, Rq(Rms), Rt, Rz and Rmax with extreme sensitivity and accuracy. )
The high sensitivity and precision of the diamond stylus enable a display resolution of up to 0.001 microns. The SRG-4500 Surface Roughness Tester uses a simple internal structure that allows for metric to inch conversion, measurement length, sample length, parameters, test level (sensor position), digital filter and much more!
The battery-powered portability allows the SRG-4500 Surface Roughness Tester to increase productivity throughout the job shop.
