Simultaneous Measurement of Multiple Components for the Emission Regulations适用于多组分同时测量排放标准

     The MEXA-ONE-FT Series simultaneously measures concentrations of several constituents including NH3, N2O, CH4,CO and CO2 in un-diluted exhaust gas using the Fourier transform infrared (FTIR) method in combination with a multivariate analysis algorithm. It incorporates HORIBA's proprietary, compact interferometer which yields superior performance and high accuracy. In addition, usability, expandability and flexibility are realized by “HORIBA ONE PLATFORM”.The system complies with NH3 testing requirements of Euro VI, the EU regulation for heavy duty emissions testing.

   MEXA-ONE-FT系列可以多组分同时测量未稀释的尾气的几个组分包括NH3，N2O,CH4，CO和CO2，利用傅里叶变换红外（FTIR）方法结合多变量分析算法。它集合了Horiba专业，紧凑，精度高特点。另外，在“HORIBA ONE PLATFORM”上轻松体现出它的易用性，可扩展性和灵活性。该系统符合欧VI，欧规重型排放检测的NH3测试要求。
