I. Purpose
The surface roughness measuring instrument is suitable for laboratories and production sites. It can measure the surface roughness of various machined parts, including flat surfaces, inclined surfaces, outer cylindrical surfaces, curved surfaces, small holes, grooves and axles, etc., according to the selected measurement The corresponding parameters are calculated according to the conditions, and the measurement results and contour graphics are clearly displayed on the liquid crystal display.
2. Features
1. Mechatronics design, small size, light weight, easy to use;
2. High-precision inductive sensor;
3. Using DSP chip for control and data processing, fast speed and low power consumption;
4. GAUSS filter;
5. 128×64 dot matrix OLED LCD screen
6. Built-in lithium-ion rechargeable battery and charging control circuit, high capacity, no memory effect, continuous working time is more than 20 hours;
7. With automatic shutdown, memory and various information;
8. Optional accessories such as curved surface sensor, small hole sensor, measuring platform, extension rod, etc.
9. Compatible with ISO, DIN, ANSI, JIS national standards;
10. The system language can be switched between Chinese and English, and the default Chinese system when booting
11. The unit can be changed in order: industrial system→imperial system; the default value is industrial system.
