We’ve been using the Tri-Gauge for about a month... I’ve conducted three training sessions.
The people that have used it are amazed with its simplicity…one man wanted to know why we didn’t buy it 10 years ago…another person mentioned that they were able to check parts without tearing down their setup.
We’re having fun.

From a volume manufacturer of high-quality motors supporting the machine tool industry:
The Tri-gauge arrived in perfect condition and on time. We have since used it extensively. Apart from there being minimal setup time the big benefit is you do not have to set up on a surface table, insert gauge blocks etc.
We have been able to go into the store and check shafts in situ. We have a lot of shafts that have been quarantined and the gauge has enabled us to check them without disturbing our processes and clogging up our area. We have checked the gauge against our first principle check and found very close correlation.
