Exhaust Gas Analyser

The Exhaust Gas Analyser is designed for detecting the five types of automotive gas emissions: CO, HC, CO2, O2, and NO.


  • It is used for measuring automotive emission gas: CO, HC, CO2, O2, and NO;

  • The LCD display features a Chinese/English operation menu;

  • The internal bench is an advanced OIML Class 0 bench from HORIBA Japan. Other sensors are high-quality global brand products;

  • Functions include auto-zero, auto-calibration, and leak check;

  • The flexible probe can accommodate almost all types of tail tubes;

  • Equipped with the latest aluminum alloy drain separator;

  • Warm-up takes only 30 seconds;

  • Auto-compensation for ambient pressure and environmental temperature;

  • Automatically calculates engine AFR, with an optional O₂ sensor;

  • Equipped with two idle test functions;

  • Capable of storing more than 200 measuring results;

  • Comes with a standard RS-232 interface;

  • Signal output for easy connection to a computer.
