We help you find the right gage for your specific part, process, and tolerance requirements. As the exclusive master stocking distributor, we maintain the largest North  American inventory of Leitech COMBI Gages and accessories —  standard sizes ready to ship, no waiting for overseas lead times.

Our engineering team will work with you to spec the right gage — and get you a quote fast.  


  • Leitech Instruments was founded by Leif Larsen, whose insight was simple and revolutionary: quality engineers shouldn't need two tools to inspect one hole. That idea became the Leitech  COMBI Gage — and it changed how precision manufacturers  approach thread depth inspection worldwide. The System Leitech has been recognized with an industrial design award from the Danish Design Council. Today, Leitech Instruments continues under the leadership of Charlotte Jensen, carrying forward  her father's legacy of precision, innovation, and customer partnership from Gilleleje, Denmark.  


  • Leitech-US is led by Mike Thorson and Tony Thorson, who together bring decades of precision measurement expertise and deep personal relationships with the Leitech Instruments team in Denmark. Represented Leitech in North America, Leitech-US has built building a network of thousands of satisfied  customers across automotive, aerospace, medical, energy, and industrial manufacturing.
