The PHASE II SRG-4000 profilometer is delivered with a compact durable carrying case, roughness standard, and instruction manual.

The newest of the state-of-the-art surface roughness testers, the SRG-4000 is built for  the shop environment. These surface roughness testers are defined by:  high accuracy, multiple parameters and operation simplicity. Extremely sensitive, highly accurate readings from this Phase II surface roughness tester are offered via multiple surface roughness parameters, Ra, Rq(Rms), Rt and Rz.

The diamond stylus is capable of .001 (um) micron display resolution. The SRG-4000 surface roughness testers 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! Measurement results are displayed as large characters on the LCD screen for easy recognition.

Battery powered, the SRG-4000 surface roughness testers add mobilize productivity throughout the shop.

Optional accessories available for the SRG-4000 surface roughness testers include:

• 2um Stylus
Extension Rod
NIST certified surface roughness standard


Menu driven operating system
4 Different roughness parameters
Inside/Outside Diameters
Stylus position indicator
RS 232 output to printer/PC
Extended memory functions
