Main Features and Specifications

1. Measure concentration of HC, CO, CO2, O2 and NOx contained in exhaust gases from gasoline engine of vehicles. Advanced NDIR (non-Dispersive Infrared) analysis technology is used to measure HC, CO, CO2 and the newest generation of electrochemical technology is adopted to measure O2 and NOx.

2. Designed with LCD screen for easier setting and operation.

3. Automatic calculation and display of A/F (air-fuel-ratio) and Lambda air ratio .

4. Emissions from vehicle engine fuels of CNG, LPG and Ethanol gasoline can be measured.

5. Small Size, light weight and most convenient for carry.

6. Designed with inductive clip-on pickup sensor for RPM measurement.

7. Designed with oil temperature measurement probe.
