EngineCheckupMDC 4-Way Test Strips (Part No. 98722) offer new technology for instant coolant analysis for four critical measurements of the status of antifreeze components, the maker said. The test strips allow shops to standardize on one version coolant test strip for antifreeze with or without nitrates, with pH test results included, the company said. Simply obtain a coolant sample from your radiator or cooling system, dip the test strip into the sample and compare the color of the pads at the end of the strip to the chart. Repeat test as necessary, before or after service. The test strips provide repeatable and reliable test results that can be compared to refractometers (to measure freeze point or glycol concentration), titration kits (to measure inhibitor concentrations) and electronic meters (to measure pH and conductivity), according to the manufacturer. Depending on test strip results, you can decide to send coolant samples for lab analysis, or use these tools for more accurate and precise (numerical) results. Other coolant test strips and kits are available.
