When oil transmittance is between 30% and 60%, an '！' will be displayed to remind you to pay attention. When oil transmittance is below 30%, engine oil quality tester will display '×' to warn you to change the engine oil to ensure safety.All three test results are accompanied by a‘beep’ sound to remind you.
【High-precision Sensor & 50inch Flexible Probe】Engine oil tester probe adopts an integrated high-precision photoelectric sensor and temperature sensor, which provides fast and sensitive response and more accurate measurement results. A 1270mm/50inches long hose probe can be bent flexibly to easily enter the dipstick hole. No need to take the oil out to test.
