These liquids, <br /> and the threshold for each, have not been determined at this time. <br /> Comparison of TLS-450 with TLS-350 series console showed comparable results when evaluated with <br /> representative sensors. <br /> Veeder-Root Evaluator: Ken Wilcox Associates <br /> 125 Powder Forest Dr. Tel: (816) 443-2494 <br /> Simsbury, CT 06070-2003 Dates of Evaluations: 05/18/04, 03/03/08, 08/04/10 <br /> Tel: (860) 651-2700 <br /> E-mail: infoc&veeder.com <br /> URL: www.veeder.com <br /> Home I Vendors: A - F Vendors: G - M I Vendors: N - S I Vendors: T - Z I Method Index <br /> Glossary I <br /> Appearance on this list is not to be construed as an endorsement by any regulatory agency nor is it any guarantee of the <br /> performance of the method or equipment. <br /> http://nwglde.org/evals/veeder—root—za.html 10/13/2017 <br />
