DEF 7-040-9 Contamination Test is a crucial solution utilized to detect contamination in various hydrocarbon fuels such as diesel fuel, oil, gasoline, and gas. Maintaining the purity of Diesel Exhaust Fluid (DEF) is essential to prevent damage or shorten the life of the Selective Catalytic Reduction (SCR) system. Our innovative DIP and DETECT test strips offer a easy to use, fast, and cost-effective solution for DEF contamination testing. Simply dip the test strip into the DEF fluid in the DEF tank, and any color change on the strip will indicate the presence of oil contamination.
