Phase II Plus Surface Roughness Tester

Portable Surface Roughness Tester


  • The PHASE II SRG-1000 Surface Roughness Tester is a pocket-sized economically priced instrument for measuring surface 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 Roughness parameter Ra or Rz at the touch of a button, combined with the selected cutoff length. External calibration of the 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-1000 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-1000 determines both Roughness parameters Ra and Rz within a wide measuring range (see specifications below). The piezo-electric pick-up stylus with diamond tip assures a very reliable measurement within tolerances that conform to ISO class 3. Roughness parameter Ra is computed to conform to ISO and Rz is computed to conform to DIN
