Keeping it simple
The Surtronic philosophy keeps the process simple. It is the perfect 
tool for any inspector to check surface roughness even in the most 
demanding applications.
• Incoming inspections
• Final inspection before shipment
• Process control on the production line
• Checking large components or structures
Standards and traceability 
The reference standard supplied can be used both to calibrate the 
instrument and check for stylus wear to ensure the most accurate 
results are always being achieved. 
UKAS calibration and testing
Taylor Hobson provides full certification for artefacts and instruments 
in our purpose built ISO graded clean room UKAS facility. Our 
UKAS laboratory is able to measure all of the parameters associated 
with surface texture, including French, German, USA and Japanese 
derivatives.
