Overview
The SD-SRT311 is a split-type surface roughness tester: the drive unit separates from the main unit for measuring positions the instrument body cannot reach, and stores inside the main unit when not in use. It measures flat, inclined, cylindrical and curved surfaces, small holes and grooves on both metal and non-metal parts, without damaging the workpiece.
A 3.5-inch 480 × 320 TFT display shows the parameter values together with a live roughness curve while measuring. Data can be sent over Bluetooth to a printer or an Android phone, or to a PC through the supplied cable. The DSP processor keeps power consumption low while maintaining a 0.001 µm display resolution.
Features
- Split design — the drive unit can be stored inside the main unit and separated for remote measurement
- Wide measuring range: 320 µm on the Z axis, 17.5 mm on the X axis
- 3.5-inch (480 × 320) TFT display with backlight and wide viewing angles
- Real-time waveform with synchronous display of the curve during measurement
- DSP chip processor — high speed, low power consumption
- Bluetooth connection to printer and Android phone; PC software via supplied cable
- KS160 axe-type standard sensor, suitable for about 90% of samples
- On-screen practical information: battery indicator, stylus position, device states, parameter settings
- On-board storage for 100 measurements
