52mm air fuel ratio counter with LED display with oxygen sensor 12V

The air fuel ratio counter is a professional diagnostic device for monitoring and optimising the engine efficiency of the vehicle. This 52mm LED digital air fuel ratio counter with a narrow range O2 oxygen sensor allows you to track the combustion process of the engine in real time. It was designed for racers and car enthusiasts who wanted to achieve maximum engine performance. The air fuel ratio counter for 12V cars is a necessary means of accurately adjusting the fuel / air mixture ratio.

Air fuel ratio counter - main features

• LED digital display - A clear, bright 52mm display shows real-time data about the engine combustion process, easy to read both day and night, provides reliable information every second.
• Narrowband O2 Sensor — OEM 0258006028 model is compatible with a range of 0-1V, ideal for engine diagnostics and tuning, providing accurate measurements for professional use.
• Rapid response - Less than 100 ms of response time (600-300mV and 300-600mV), provides the most expeditious data about the state of the engine and allows rapid response to changes.
• Durable components - Built-in heating resistance of 8,5- 9,5Ω and an internal resistance of 200- 300Ω guarantees durability and stable operation in difficult conditions.
• M18 × 1,5 thread with 22mm key - Universal connection, suitable for many car models, easy to install without a special tool, 10 seconds after switching on.
• High compatibility - Works with Geely Emgrand, Citroën, Fiat and Peugeot cars as well as other 12V cars that have a narrow range of oxygen sensor systems.
• Professional cable diagram - Colour marked cables (white, black, grey, green) with clear connection instructions, reduces the risk of connection errors and speeds up installation.
