Today’s Extended Life Coolants require periodic lab testing. There is not a field test that can accurately measure dilution and contamination. The PTK-103 is the only test kit that will perform a ‘LEVEL 5’ test. This is imperative for NOAT and OAT coolants! Penray provides cooling lab test kits for times when more detailed analysis is needed than a test strip can provide. All lab tests are performed by an independent laboratory. After submitting your sample, a detailed analysis sheet will be provided along with individual recommendation treatment/mainteance plan from our coolant experts.
