USB Connectivity
Through its industry standard Type A USB port and mini USB port the SR series instruments provide extensive connectivity options to many standard devices.

Profile graph
Detailed graph shows measured area to help identify problem areas

Any surface, any height
Even the most challenging surfaces can be measured without the need for expensive riser blocks, stands or fixtures. The stylus can even measure upside down!

The inclusion of a 50mm stylus lift with rightangle attachment and more than 70mm stylus reach. The anti-slip V-feet also mean the system can be used on flat or curved surfaces.
