It has been my good fortune to have in Tri-State Instrument Service a valued asset to my metrology program for many years. They became my go-to for accredited calibration services, both onsite and at their facility. Their wide representation of manufacturers of the best in measuring equipment as well as hard gaging combined with their ability to provide accredited certification where required has always given me confidence I was supplying the best to my customers on the production floor. Their support after the sale is greatly appreciated, as well. They have reliable repair services and can assist a world-class metrology program with a great depth of professional knowledge.

Over the past 15 years I have worked in calibration in three different locations.  Each place I have gone to, I brought Tri-State with me. Any time I need to contact anyone at Tri-State I feel like I’m calling a friend.  I always know I will get the best quality product with the best pricing and service.  I’ve had several occasions where I was uncertain how to solve a gauge related problem and the entire team (Cathy, Eric, Lyn and Stuaghton) have always been very quick to respond, honest and willing to help me in any situation I may have. From calibrations to calibration repair to new gauge ordering; Tri-State Instruments will always be the team I want on side.
