Product Introduction<\/b><\/strong><\/p>\n

\"\"<\/p>\n

The ambient air NMTC continuous automatic monitoring system consists of sampling manifold, pretreatment unit, analytical instrument, hydrogen generator, zero gas generator, air compressor, meteorological parameters, dynamic calibrator, electronic control unit, etc. It adopts the direct measurement method of cold trap enrichment to monitor the NMTC organics, which features\u00a0low detection limit and good reproducibility. It can be applied\u00a0in the industrial parks and the regions.<\/p>\n

This equipment\u00a0has higher reproducibility of VOCs components and smaller system drift\u00a0and it can sensitively capture the complex and subtle changes of VOCs components in the boundaries of the enterprise or ambient air in real time. And real-time on-line monitoring of total hydrocarbons, non-methane total hydrocarbons, and methane and other indexes\u00a0can be realized. At the same time, it meets the requirements of online data analysis, reporting and remote transmission of relevant national ambient air quality monitoring standards, and combines meteorological temperature, relative humidity, wind speed, wind direction, barometric pressure and other parameters to provide a scientific basis for the assessment of the pollution status of the characteristics of the VOCs in the regional ambient air and the trend of change.<\/p>\n

Technical characteristics<\/b><\/strong><\/p>\n

\u2b50 The sampling pre-treatment system adopts constant temperature accompanied by heat to avoid condensation of water vapor in the sample gas\u00a0and affect measurement concentration of the sample gas.<\/p>\n

\u2b50\u00a0Perfect combination of dynamic curve tracking correction function (DCC) and multi-point calibration technology.<\/p>\n

\u2b50 Simultaneously measure the five parameters of environmental meteorology, total hydrocarbons, methane, non-methane total hydrocarbons.<\/p>\n

\u2b50\u00a0It can be equipped with explosion-proof instrument cabinet, suitable for explosion-proof occasions installation requirements.<\/p>\n

\u2b50 The use of silanized gas piping greatly reduces the adsorption of gas samples in the pipe wall.<\/p>\n

\u2b50\u00a0Intelligent FID detector flame out self-ignition alarm function, which enables\u00a0effective safety control\u00a0of hydrogen flame gas lines.<\/p>\n

\u2b50 This analyzer supports multi-detector configuration to improve the application range of the analyzer.<\/p>\n

\u2b50\u00a0TCP\/IP network for remote control of the analyzer\u00a0and\u00a0on-site operation\u00a0by touching the LCD screen.<\/p>\n
