Hangzhou Chunlai Technology CO., Ltd. products

The VGT-400 portable vehicle exhaust gas tester is a series of vehicle exhaust gas detection products developed and designed by our company in accordance with the requirements of the new national standards (GB18285-2018, GB3847-2018), which are specially used for road random inspections.) Detection of NO, NO2 concentration, non-dispersive infrared absorption technology to detect HC, CO, CO2 concentration and electrochemical cell technology to detect O2 concentration, suitable for gasoline and diesel fuel vehicle exhaust detection.

The mobile vehicle exhaust telemetry system independently developed by our company is suitable for urban road mobile monitoring and single-lane fixed monitoring. The detection of CO, CO2, NO, HC, opaque smoke and light absorption coefficient in gasoline and diesel vehicle exhaust is realized by tunable semiconductor laser absorption spectroscopy technology, ultraviolet differential absorption spectroscopy technology, green laser transmission principle and high-definition image recognition technology, the response time is fast(less than 0.5s), and the system operation is simple. The remote sensing monitoring method is used for monitoring, which does not affect the normal driving of the vehicle, avoids the interference and uncertainty caused by sampling, and the monitoring results are objective and true. The measurement signal is transmitted through WI-FI, and an external LED display can be connected to display the exhaust emission information of the vehicle.

The ERMS2000-F horizontal stationary vehicle exhaust remote sensing system, developed by our company, is suitable for stationary enforcement of city roads. It can detect the CO, CO2, NO, HC and opaque smoke intensity in gasoline and diesel vehicle exhaust with fast response time (<0.5s) as well as simple system operation. Coordinating with the micro environment air station system, can collect external environment information and eliminate background interference. The measured signals are transmitted through WIFI, and it can be connected to the LED screen to display vehicle exhaust emission information. Dispensing with sample extraction, the technology avoids the interference and uncertainty from sampling to reflect the pollution condition of vehicle exhaust emission objectively.
