NSI Inc. Instrumentation Repair

In the mid 1950’s, John B. Nichols started learning and specializing in instrumentation repair on American and Foreign cars. In 1962 he established Nichols Speedometer and Instrument Company.  In 1976 his son Charlie Nichols stepped up to lead the company in new directions for sales and service, and Nichols Speedometer continued to provide top notch repair options for its customers. As it was then, just as today, vehicle instrumentation repair requires special tools and equipment to diagnose and correct problems caused by devices that most mechanics and dealers would just have to replace.  Our company allows vehicle owners, mechanics, and dealers a new option. Repair original equipment, rather than replacing it. 
In 2006 Nichols Speedometer has become NSI Inc., and now we have three generations of instrumentation repair experience.  As cars and trucks have changed over the years NSI Inc has adapted to keep up with the world of instrumentation. With over 40 years of combined knowledge NSI should be able to help find a solution to your vehicles instrumentation problems no mater if they happen to be a mechanical speedometer from a vintage restoration or an electronic/computerized cluster for a newer car or truck.  Call us for consultation on your personal instrumentation application or problem.  We will be happy to help.
