Engine Oil Tester Gasoline & Diesel Engine Oil Quality Tester Analyzer Detector High-precision Car Engine Oil Diagnostic Tool with 50inch Flexible Probe,Identifier&Sound Prompt,2.8in Backlight Display

【Why You Need Engine Oil Tester】Engine oil tester can help you check your engine oil regularly to ensure you are driving in a safe condition, helping to extend the life of your car. Failure to replace engine oil in time and poor quality oil will reduce lubrication, reduce sealing effect, reduce cooling effect, and reduce cleaning effect.
【2s Fast Oil Quality Detection】Engine oil tester can quickly measure oil transmittance in 2s to determine if there are impurities or metal powder, and whether engine oil needs to be replaced.The more impurities in engine oil, the lower the transmittance. To prevent impurities from settling and causing inaccurate measurements, pls make sure to shake up your used oil bottle before testing it. If you test the oil in the vehicle, run the engine for one minute to circulate the oil and then test it.
【Applicable to Various Engine Oils】Our engine oil quality tester is compatible with various lubricant oiI standards, suitable for most gasoline and diesel engine lubricant oil on the market. Separate sampling and measurement of gasoline engines and diesel engines can more accurately determine the health status of lubricant oil.
【Identifier & Sound Prompt】Engine oil analysis kit can generate a analog bar graph. When the engine oil transmittance is between 50% and 100%, the engine oil tester screen will display 'OK'. When oil transmittance is between 30% and 50%, 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. The hose is made of PTFE material, which is highly resistant to oil, oxidation and corrosion, effectively extending its service life.
