The TIME 3221 is an advanced surface roughness gauge that is a comprehensive testing device. It is designed to allow testing of most test samples and surfaces - especially difficult to access and intricate shape work pieces.

A separate stylus housing connected by a long fly-lead, allows for measuring the roughness of inside or outside of bores on small diameter pipe or tube, stepped gears, o-ring grooves and recessed notches.  Industry examples include measuring roughness of cylinder heads, engine block bore hone or brake discs in Automotive OEM; checking finish of rail track after refurbishment and machined finish on oil & gas pipe line flange faces to ensure correct fit and seal.

The TIME3221 uses a diamond tipped stylus that accurately traces the surface of the material by measuring the vertical deviations from a uniform centre line. It is able to display the results under many parameters including Ra, Rz, Rq, Rp, Rv, Rsk, Rmr to name a few.  

The results are displayed on the large, high resolution colour LCD, including the waveform trace of the surface. Test results can be saved to internal memory and managed with the TimeSurf Windows software which is an optional extra add-on.
