R7000 Surface Roughness Tester

$2,250.00

The new touch-screen PTc R7000 Surface Roughness Tester is capable of determining 45 roughness parameters. Stored test results & surface profiles can be outputted to a PC.

The new touch-screen PTc R7000 surface roughness tester is suitable for use in laboratories, factory metrology rooms, quality control areas and the manufacturing floor.

For testing the surface roughness of various machined components, this instrument allows the user to select as many as 45 roughness parameters such as Ra, Rz etc.

The test results, including surface profiles, are stored in the R7000 unit and can be outputted to a PC.

Typical Applications

Tests are performed on machined and ground metal parts in a variety of manufacturing operations, quality control areas and laboratories to evaluate the surface quality.  Some non-metals are amenable to testing with a stylus-type unit such as the R7000.  Sometimes the stylus is unable to perform its function because of excessive surface friction or gouging such as in attempting to test rubber.
