Portable Surface Roughness Tester

Hand Held Surface Roughness Tester High Accuracy 

Introduction:

TMR201 Hand-held Surface Roughness Tester is a new generation of Surface Roughness Tester Series. It features high accuracy, wide application, simple operation, portability and stable performance. The tester is widely used in measuring the surface roughness of various metals and non-metals.

Application:

Machining process control: grinding, turning, milling, honing, polishing, etc.

Heavy industry: shipbuilding, aerospace, pipeline, steel plate

Aerospace: turbine blades, turbine shafts, wings and other composite materials.

Others: Printing roller, floor, and glass.

Features:

  1. High-speed ARM+DSP processor with low power consumption, strong computing power and fast calculation speed, and the result will be available within 1 second after the travel. No need to wait.
  2. Collect thousands of data’s in the distance of travel to accurately reproduce the surface of the workpiece.
  3. Precise digital filter. Ensure machine repeatability is less than 2%.
  4. 10% accuracy error in line with the national standard.
  5. Adapt to high temperature, high humidity, high vibration working environment.
  6. The test results can be traced back to the roughness parameters of the national benchmark.
  7. Diamond touch needle, strong and durable.
  8. Unique software processing. Start the test immediately, no need to wait.
  9. Precision inductive bridge sensor with resolution up to nanometre level.
Characteristics:
