SR230 Surface Roughness Tester

  • Compact mechatronic design for easy portable use.
  • DSP-based control and data processing for fast response and low power consumption.
  • Supports multiple standards including ISO, DIN, ANSI, and JIS.
  • Large-capacity memory for storing up to 100 sets of raw data and waveforms.
  • Real-time clock for measurement record and storage management.
  • Auto sleep and auto shutdown for power saving.
  • PC and printer connectivity, with optional Bluetooth.
  • Optional accessories available for curved surfaces, small holes, measuring platforms, sheaths, and extension rods.
The HIKOTEK SR230 Surface Roughness Tester is a high-precision portable instrument designed for checking the surface smoothness of machined parts. It can be used on flat, inclined, cylindrical, and curved surfaces, and is also suitable for small holes, grooves, and shafts.
