John B. Nichols, Jr. established Nichols Speedometer Service in the mid 1950’s and was sole proprietor until he was joined in partnership with his son, Charlie, in 1976. Under Charlie’s leadership, the company, now known as NSI, Inc. continues to grow and diversify.

Our goal is simple; we want to match your needs with the finest equipment that we know of on the market today. We will then back up what we sell you with service. We are your one stop shop for anything related to vehicle instrumentation.

From its inception in 1962, Nichols Speedometer & Instrument (NSI) has sought to provide our customers with first class products backed by first class support. We are now the master distributor in the USA and Canada for all VDO tachographs and related accessories. We also offer a full line of on-board computers, including GPS-based systems. Finally, we can handle all of your vehicle instrumentation needs, from speedometers to fuel gauges. In fact, we are the East Coast’s authority on VDO gauge service and installation.

Our Company is small enough to give you personalized service, yet large enough to leverage top purchasing power for great product selection at market competitive prices.

Let the professionals at NSI help you evaluate your needs and propose the most cost effective solution. We are eager to earn your business and have you join the extensive list of satisfied NSI customers.
