A corrosion inhibitor is a chemical compound or substance designed to mitigate or prevent corrosion, which is the deterioration of materials, particularly metals, due to chemical reactions with their environment. These inhibitors work by forming a protective layer on the metal's surface, blocking or slowing down the corrosion process. Corrosion inhibitors find extensive use in industries such as manufacturing, oil and gas, transportation, and infrastructure to prolong the lifespan of equipment, pipelines, and structures, ultimately saving costs and ensuring safety. They play a crucial role in safeguarding the integrity and functionality of metal components exposed to corrosive conditions, such as moisture, chemicals, or extreme temperatures.
Easy-to-Read Color Chart Each strip measures concentrations between 10-200ppm (parts per million), with color matches at 10, 50, 100 and 200ppm. The distinct color chart and accurate, reproducible readings give an immediate response for quick and easy use. Meets Requirements Federal, state, and local health regulations require users of chlorine-based sanitizer solutions to have appropriate test kits available to verify the strength of sanitizer solutions. This kit meets those requirements. Easy to Use The distinct color match at each full unit makes it easy for the user to detect exhaustion of solutions that should be replaced. It also helps avoid the use of excessive amounts of sanitizing agents, to avoid wasting product! Simply remove a strip from the vial, dip the strip into the sanitizing solution, blot with paper towel, then instantly compare the resulting color with the color chart. Accurate Sanitizer solutions are essential in the food service industry. These strips ensure that those sanitizers are at the proper concentration. For accurate results, store these test strips away from areas with high humidity or where they may be exposed to water before use, as those conditions may compromise results. dditional information Weight 0.03 lbs Quantity 1/Each Type Chlorine Test Strips Package Size 100 Pieces Test Level 10 â?? 200 PPM
