- Model ERMS-2000 - Vehicle exhaust remote sensing system

Vehicle exhaust remote sensing system receives more attention and reliability with its advantages of speediness, convenience and wide monitoring range,etc. It can monitor exhaust gas towards gasline venhices as welll as diesel vehicles on the road and identify the high-emission vehicles among moving vehicles without affacting normal running. The system connects monitoring data, vehicle emission information and exhaust annual inspection data through modern communication technology to realize integrtaed management for vehicle emission data. For vehicle pollution prevention and management department as well as vehicle inspection institution, the establishment of the system can provide system support for general management towards the data of the road exhaust pollution condition, over-emission vehicle capture and inspection data at detection field for specific vehicle.

Adopts self-developed TDLAS and DOAS monitoring technology
Simple operation, fast response(less than 0.8s), less maintenance
Narrow-band radar speed measurement, strong anti-interference ability, high measurement accuracy
Multiple points identification of vehicle position in vertical, accurate capture of exhaust gas monitoring
Calibration system integration, simultaneous calibration for four components, support both manual and auto calibration
Highly integrated design, small size and light, realize fast on-site deployment
