## Description

CMTOOL Engine Oil Tester Kit Gasoline & Diesel Engine Oil Quality Test Kit, Quick Testing Transmittance and Temperature, with 31.5 inch Flexible Probe

## Features

- 【Transmittance Test and Oil Temperature Measurement】Inserting the probe into the oil tank to test the transmittance can reflect the impurities or contaminants contained in the oil and facilitate diagnosis of the quality and performance of the oil. The engine oil quality tester also has a built-in high-precision temperature sensor to measure the actual temperature of the engine oil, which can reflect the working status and load of the engine. Temperature measurement range: -10℃~125℃ (14℉~257℉).
- 【Dual Test Mode For Wide Application】The engine oil quality tester can choose between gasoline engine mode and diesel engine mode to meet diverse testing needs. This engine oil tester is used to detect the lubricating oil of most gasoline engines and diesel engines on the market. It can sample and measure these two types of oil separately to more accurately diagnose the oil condition.
- 【80cm High-Quality Hose With High Precision Probe】The hose is made of high-quality Teflon material, which is highly resistant to oil, oxidation and corrosion, and has a longer service life. The 800 mm (31.5 inches) hose makes the oil quality tester more flexible in testing. The probe uses a photoelectric transceiver sensor probe, making the measurement results more accurate and reliable.
- 【2.8-Inch Backlight Screen and User-Friendly Design】The car oil quality tester is equipped with a 2.8-inch LCD backlight display, which can adapt to environments such as strong light or darkness. The measurement results are clearly visible, helping users complete their work easily and comfortably. The handheld part of the engine oil tester is made of silicone substrate, which is comfortable and stable to hold, and can be easily operated with one hand.
- 【Battery Powered and Automatic Shutdown】The engine oil quality tester is powered by 4pcs 1.5V AAA batteries (included with the tester), and the battery compartment symbol in the upper left corner of the screen will display the battery power. If there is no operation for 5 minutes, the engine oil quality test device will automatically shut down to save power.
