Overview
The pocket surface roughness instrument NDT110B is a Portable testing instrument that complies with GB/T 3505-2000 and GB/T 6062-2002 national standards, suitable for the measurement of surface roughness of metal and Non-metallic parts. The instrument adopts a high-speed DSP processor, has the characteristics of High Accuracy and fast measurement, and will not damage the workpiece. It is especially suitable for on-site inspection of large workpieces and production lines.
Features
1. Choose from 2 (Ra, Rz) or 4 Measurement parameters (Ra, Rz, Rt, Rq)
2. Optical inspection Glass matrix for calibrated samples, identified by the National Institute of Measurement, high accuracy, not easy to scratch, long service life
3. Adjustment, simple operation
4. High-speed DSP processor for data processing and calculation, fast speed, higher accuracy
5. Optional sampling length 0.25mm, 0.80mm, 2.50mm
6 point array LED liquid crystal display, high luminance, no viewing angle, wide temperature, suitable for various occasions
7. Automatic shutdown function and low power consumption software and hardware design make the instrument Working time super long
8. Two charging methods, special charger or computer USB port charging, can work while charging
9. Sensor probe with protective door, effectively protect Sensor probe, ensure Measurement accuracy
10. The shape is designed with a drawn aluminum die, which is sturdy and durable, and has significant resistance to electromagnetic interference
11. After strict temperature and Humidity test, adapt to high temperature and high Humidity working environment, the southern humid climate measurement is not affected
Principle
Measurement principle of contact (stylus) is adopted. Sensor probe moves on the surface of workpiece, and the profile data is processed and calculated by high-speed DSP processor to obtain surface roughness parameters. The measurement process conforms to the surface structure evaluation standard of contour method to ensure the accuracy and Reliability of measurement results.
Applications
Detection of surface roughness of metal and Non-metallic parts to be tested, inspection of various machined parts, machining manufacturing, inspection, commodity inspection and other departments, on-site inspection, inspection, Measurement, commodity inspection and other departments of large workpieces and production lines
