Zetian - Model VGT-100V - Vehicle Emission Tester
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.
- Adopt direct optical method to measure NO2, solve the problem that conversion efficiency of traditional converterwill reduce over time.
- Response time of NO and NO2 is less than 3s.
- Adopt UV-DOAS technology to measure NO and NO2 simultaneously without interfering by background gases like moisture.
- With multiple interfaces to connect to parameters including oil temperature, rotational speed, ambient temperature & humidity and pressure, etc.
