Handheld Surface Roughness Tester Profilometer

The PHASE II SRG-2000 surface roughness tester profilometer is a pocket-sized economically priced instrument for measuring surface roughness texture conforming to traceable standards. It can be used on the shop floor in any position, horizontal, vertical or anywhere in between.

The large LCD display shows either surface roughness parameter Ra, Rz, Rms(Rq) and Rt at the touch of a button, combined with the selected cutoff length. External calibration of the surface roughness values is possible by means of a special CAL button, which makes adjustment of this instrument very easy. A beep signal informs the user about each individual measurement status when ready.

The easy to use SRG-2000 surface roughness tester profilometer operates on various surfaces, not only flat but also outer cylinder, outer cone, grooves, and recesses greater than 80x 30mm. The areas of application are wide spread. It is suitable for inspection departments, quality control, on the shop floor during machining, during assembly, and on site.

The SRG-2000 determines surface roughness parameters Ra,Rz, Rms(Rq) and Rt within a wide measuring range. The piezo-electric pick-up stylus with diamond tip assures a very reliable measurement within tolerances that conform to ASME B46.1. Surface Roughness parameter Ra is computed to conform to ISO and Rz is computed to conform to DIN.

The PHASE II SRG-2000 surface roughness tester profilometer comes complete with a compact durable carrying case, roughness standard, charger and instruction manual.

Portable Surface Roughness Tester Profilometer

The newest addition to our state-of-the-art surface roughness testers profilometer, the SRG-4500 will instill the highest level of confidence in your production, shop floor or QC lab. Extended memory and output coupled with multiple useful functions the SRG-4500 surface roughness tester profilometer is clearly the new leader in ultra accurate surface 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 profilometers are offered via 15 popular surface roughness scales including Ra, Rq(Rms), Rt, Rz and Rmax.

The diamond stylus is hypersensitive and sophisticated enough to allow for a .001 (um) micron display resolution. The SRG-4500 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! Measurement results are displayed as large characters on the LCD screen for easy recognition.

Battery powered portability allows the SRG-4500 surface roughness testers profilometers to mobilize productivity throughout the shop.
