Key features

• •【Transmission Fluid Testing】Our transmission fluid tester features an advanced optical probe that measures light transmittance in the fluid, instantly detecting metal wear particles, friction coefficients, and viscosity degradation to assess oil integrity and transmission performance.
• •【Broad Compatibility】This transmission fluid tester meets all industry standards, enabling repair shops, fleets, and DIY users to optimize fluid change intervals with lab-grade accuracy. Internal field tests show it reduces maintenance costs by 18–35%.
• •【Transparency Analysis】This transmission oil tester is used to measure the light transmittance of transmission oil and reflect impurities, contaminants or deposits in the oil. When the light transmittance is between 100% and 50%, it displays [OK]; when between 50% and 30%, it displays [ ! ]; when below 30%, it displays [ X ].
• •【High-Precision Optical Probe】 Equipped with advanced photoelectric detection for laboratory-grade results.
• •【Probe & LCD】800mm probe for flexible testing. PTFE hose resists oil, oxidation, and corrosion, extending lifespan. 2.8 - inch LCD offers clear visibility in all light conditions.
• •【Notes】Before each measurement, wipe the probe clean and ensure engine temperature is below 60°C (140°F). When installing batteries (4x 1.5V AAA), observe correct polarity.
