² CO/CO2Adopting tunable semiconductor laser absorption spectroscopy technologyTDLASMeasurement technology,NO/HCUsing ultraviolet light source for differential absorption of light to reduce smoke intensity/The light absorption coefficient is measured using the principle of green laser transmittance;

² The telemetry system equipment has a long detection distance, and the vertical detection distance is not less than6Rice;

² Fully automatic monitoring, unmanned operation, low maintenance, high reliability.

² Installation method: Vertical fixed installation, unmanned, with day and night detection function.

² Detection rate: When the car is accelerating, the effective capture rate is greater than when the exhaust pipe is rear mounted or under intermediate conditions85%；

Repeatability:CO、CO2、HC、NOxThe repeatability error of opacity monitoring shall not exceed ±5%.

² The measurement response time is not greater than0.7In seconds.

² The system has automatic calibration function and does not require manual operation.

² The system has a built-in reference module and performs dynamic compensation to lock the gas absorption spectral lines in real-time, unaffected by temperature, pressure, and environmental changes, and the system has no drift.

² The host has intelligent self checking and self recovery functions, and the software can automatically detect abnormal measurement states of the analyzer. Through self checking and self recovery, the analyzer can be restored to its optimal measurement working state.

² Using multi-point laser path measurement technology to measure velocity and acceleration.
