Surface Roughness Tester

Model No. SRG-2200

w/Bluetooth Data Output!

Shown w/ Optional Vise Parameters: Ra, Rms, Rt and Rz
SRG2000-VISE Optional Vise

The New Phase II SRG-2200 Mini Surface Roughness Tester is a next generation of surface roughness tester developed by the Phase II Metrology Group that features high accuracy, a wide range of application, simple operation and stable performance. It is widely applicable in surface roughness testing all kinds of metals and non-metals.

Large memory with data output via Bluetooth.

The 1.14” IPS TFT display shows choice of surface roughness parameter Ra, Rz, Rq and Rt at the touch of a button, combined with the selected cutoff length. External calibration of the surface roughness value is possible by means of a built-in calibration feature which makes adjustment of this instrument very easy. Data output via Bluetooth makes saving surface roughness results fast and easy.

The easy to use SRG-2200 surface roughness tester 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 PHASE II SRG-2200 surface roughness tester comes complete with a compact durable carrying case, surface roughness standard, data output software and instruction manual.
