The instruments we offer have never been used. New Surplus ITT Barton instruments were manufactured by ITT Barton. Then purchase by the U.S. Government for stock. The Gov't sold some of its inventory, which we purchased. We supply each New Surplus ITT Barton instrument with a warranty equal to any original warranty which you would have received if you had purchased the product from the original manufacturers. The only warranty which you will receive for the New Surplus ITT Barton instruments for sale on this website, are the warranties from DPI Inc. ITT Barton branded instruments are no longer manufactured. Our goal is to make our New Surplus ITT Barton instruments more attractive than buying a comparable new instrument from a current manufacturer. Compare our price and delivery to current manufacturers of comparable instruments. Our instruments come calibrated with certs traceable to N.I.S.T.
If we don't have the unit you specify in stock, we will source it from our network of new surplus dealers. The object is to get you what you want as fast as we can. The new surplus market is a fantastic resource.
