The Q In Q-Mark Stands for Quality

What does the word "quality" mean to you? 


Most people associate quality with good design, skilled workmanship, and product reliability.  Every day, hundreds of world-class manufacturers maintain quality by using our products to help them monitor some of their most important manufacturing processes.

We make our products in California, USA.  We drill the balls, grind the carbide, and machine the metal.  We assemble each stylus.  We deliver thousands of different probe tips every year.


We are a quality organization in compliance with the ISO 9001:2015 standard.  Our clients tell us that we have the "Best Service in the Industry".


We repair worn styli.  See our Client Benefits page for details.
