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. And they are really nice people, too
