R-2000 Portable Surface Roughness Tester

On the basis of unique split type design, the R-2000 portable surface roughness tester is applied to measure a variety of tested surfaces that are difficult to contact. With the help of various optional measuring heads, the roughmeter is able to measure flat surface, curved surface, stepped surface, pipe internal surface and so on. The roughness measuring device is suitable for a variety of production fields. It may clearly display all the measured parameters on a LCD according to selected measuring conditions.

Features
1. The surface roughness tester adopts mechanical-electrical integration design, and comes with small size, light weight and easy operation.
2. The built-in standard RS232 interface allows connection with a PC.
3. It is provided with automatic power-off function.
4. The operator can turn off the device manually. In addition, it will automatically power off if there is no operation on the keyboard for 5 minutes.
5. It is capable of memorizing 7 sets of measured data and measuring conditions, allowing for looking up or online processing next time.
6. The surface roughness tester supports switching between metric and imperial system.
