Surface Roughness Tester SHT-180
- Brand Oceanus
- Type SHT-180
The surface roughness tester used to test the parts surface roughness in the lab or production field, including of the plane, inclined plane, cylindrical surface, surface, small hole, groove and axle. According to the selected measuring conditions, the corresponding parameters are calculated, and the measurement results and contour figures are clearly displayed on the LCD screen.
Feature:
1、Small size and light weight, easy operation.
2、High accuracy sensor.
3、Using the DSP chip to control and data processing with high speed and low power consumption.
4、GAUSS wave filter.
5、128×64 FSTN LCD, Ultra-low power consumption.
6、Built-in rechargeable lithium battery could continuously work for more than 20hours.
7、With the function of auto power off and storage the data.
8、Optional curve sensor, small hole sensor, measurement platform, etc
9、Compatible with ISO, DIN, ANSI, JIS standards.
10、Language could be adjusted from English/Chinese.
11、Units could be changed in order: Metric system to Imperial system; the default is Metric system.
