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 gasoline vehicles as well as diesel vehicles on the road and identify the high-emission vehicles among moving vehicles without affecting normal running. The system connects monitoring data, vehicle emission information and exhaust annual inspection data through modern communication technology to realize integrated 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 road exhaust pollution condition, over-emission vehicle capture and inspection data in detection field for specific vehicle.

Car emissions test equipment can divided into mobile remote sensing system and stationary remote sensing system.

Overview

Hygronom is also called gas moisture meter or dew-point meter, which is used to measure the humidity of flue gas emitted by pollution source. According to measured humidity, it converts wet gas concentration into dry gas concentration. In addition, it also can be used in industrial online humidity monitoring.

HM-100 flue gas hygronom is equipped with an internal high-precision capacitance digital temperature & humidity sensor. The installation method adopts the in-situ immersion installation. It is a self-developed product, of which, the core component is from Switzerland. Put the sensor inside stack to get in touch with flue gas. The probe needs preheating to prevent gas from condensation, which will affect the measurement of moisture in the flue gas. After gas contacts with the measurement chip, the chip will change capacitance to measure flue gas concentration.

Features Of HM-100 High-temperature Hygronom

• The product is convenient for installation, disassembly, and cleaning with small and compact structure
• Direct and simple key operation on site
• The probe is equipped with heat tracing function to prevent condensate water from damaging humicap and thermal resistance

Continuous Emission Monitoring System (CEMS) consists of particulate matter monitoring subsystem, gaseous pollutants  monitoring subsystem , flue gas parameters monitoring subsystem, system control and data acquisition and processing subsystem. It can monitor gases such as SO2, NOx, O2, dust, temperature, pressure, flow rate, humidity, etc. It can also be extended for a specific occasion to monitor HCl, HF, CO, CO2, NH3, H2S, Cl2, VOC and other parameters. The measured gas passes through sampling probe for dedusting, heating tube for sampling, then goes into the gas analysis module (violet differential optical absorption spectroscopy (DOAS) for analysis measurements. It effectively solves the technical problems of dust and moisture interference on measurement, particularly in the case of low concentration measurements with an unparalleled advantage.

It applies to the emission monitoring and process analysis of coal-fired power plant, garbage power plant, cement, glass, lime factory, ceramics factory, sinter, coke oven, the process of desulfurization and denitration technology.
