National Instrument Supply Co. was founded in 1986 by Brian and Marian Feys in Nashville, TN. In December of 2012, the company went through an acquisition and became known as NISCO, Inc. The core mission remained the same: to provide customers with quality instrumentation through professional yet personable service. Over the past 30 years, NISCO has earned the reputation of being one of the most well-respected distributors in the US. Our goal has been and remains to be the best supplier of flow control products to distribution. NISCO is located in Duluth, Georgia and has eight shipping locations across the country. We are your #1 source for pressure, temperature and controls for the industrial and commercial marketplace. As a master distributor for Trerice, Wika, Ashcroft, US Gauge, NoShok, Ametek, Weksler, McDaniel Controls, Tel-Tru, Watson McDaniel, Asco and other MRO products, we keep a large inventory that is available from our stock and from our vendors for immediate delivery. What sets NISCO apart from other suppliers is our ability to offer competitive prices, product knowledge with technical expertise, and exceptional customer service.
