1. More Powerful Detection Range: Transmittance Detection: Measure the oil transmittance (0-100%) through optical technology, visualize the degree of oil contamination, to help users scientifically judge the oil change cycle.2. Dual-mode Adaptation: The engine oil quality tester supports both gasoline engine and diesel engine oil type detection, covering the needs of mainstream car models. Switchable degree Celsius/Fahrenheit units, real-time display of oil temperature, to ensure that the engine is at a safe temperature (less than 60 degree Celsius) during testing.
3. Precision Test and Sensitive Probe: The testing hose is made of oil-resistant material, which prevents chemical oil corrosion and prolongs the service life. Length of 800mm, easy to go deep into the dipstick hole or oil sump sampling. Adopting high-precision sensors, stable signal transmission ensures no interference with the light transmission rate data.
4. Easy Instant Read: 2.8 inches high resolution screen, instant display result, large display with backlight, easy and clear reading in sun or night. The LCD screen intuitively displays the light transmission rate, temperature, oil type and status prompts (e.g. warning symbols), without professional interpretation.

Weak, not heavy duty
Color: Orange4pro
Not for heavy duty use. Magnets are weak. They wouldn’t even hold a shop vac hose.
