Lambda Sensor Educational Trainer MSLAMB01

Compact and mobile trainer designed to demonstrate the operating principles of zirconia-type lambda (oxygen) sensors used in automotive exhaust systems. The trainer includes a functional sensor exposed to simulated exhaust heat and variable air-fuel ratios. Real-time output voltage changes are displayed via LED bar and external multimeter connection points. Manual controls allow mixture simulation from rich to lean conditions. Integrated educational diagrams support visual understanding of closed-loop fuel control systems.
