Automotive Emission Analyzer (4-gas/portable)

Main Features and Specifications

1.Measure concentration of HC, CO, CO2,and O2 contained in exhaust gases from gasoline engine of vehicles. Advanced NDIR (no-Dispersive infrared ) analysis technology is used to measure HC, CO, CO2 and the newest generation of electrochemical technology is adopted to measure O2.

2.Designed with a large 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.

5.700 groups of measurement data storage , which includes HC ,CO, CO2, O, N, and T.

6.Saving measurement data to USB disk with file format of Microsoft  Excel.

7.Design with inductive clip-on pick sensor for RPM measurement.

8.Designed with oil temperature measurement probe .

9.Designed with RS-232C digital serial interface.

10In compliance with accuracy request of ISO 3930 or OIML r99 Class 0. ram
