VGT-100V Vehicle Emission Tester is a product designed on the basis of Vehicle Mass Analysis System(VMAS) of gasoline. It is used to measure concertration of exhaust gas discharged by vehicle engines, including NO, NO2, CO, CO2, HC, O2, etc. Among which:
- the measurement of NO and NO2 adopts UV DIfferential Optical Absorption Spectroscopy(UV-DOAS)
- the measurement of CO, CO2 and HC employs Non-dispersive Infrared ABsorption Technology(NDIR)
- the measurement of O2 uses Electrochemical cell technology
