The newest addition to our state-of-the-art surface roughness testers /profilometers, the SRG-4600 will instill the highest level of confidence in your production, shop floor or QC lab. Extended memory and output coupled with many updated useful functions, the SRG-4600 surface roughness tester/profilometer is clearly the new leader in ultra accurate surface roughness/profile testing. These surface roughness testers/profilometers are distinguished by a high level of accuracy, multiple parameters and simplicity of operation. Extremely sensitive and highly accurate readings from this Phase II surface roughness tester/profilometer is offered via 9 popular surface roughness scales including Ra, Rq(Rms), Rt, Rz and Rmax. The new diamond stylus is hypersensitive and sophisticated enough to allow for a .001 (um) micron display resolution. The SRG-4600 surface roughness tester/profilometer can utilize an easy interface to allow for changes of in/mm (uin/um), cutoff length, sampling length, parameters, level of test(stylus position), digital filters and more! Surface roughness measurement results are displayed as large characters on the LCD screen for easy recognition. Battery powered portability allows the SRG-4600 surface roughness tester/profilometer to mobilize productivity throughout the shop.Further, a wireless Bluetooth auto-start comes standard with each unit.
