Product advantage
 
Anti-interference and high precision: We choose the strongest absorption line of ammonia in the middle and far infrared band, which is completely free from cross interference of H2O, SOX, COX, CXHY, NOX and other molecules.
 
There is no need for on-site dimming correction: the original MIR-SHORTTM ultra-short optical path gas absorption cell avoids frequent optical maintenance troubles, and the optical-mechanical structure is not affected by thermal deviation in high temperature environment.
 
High reliability and easy maintenance: high light transmission efficiency of absorption tank, high dust and high saline-alkali crystallization of industrial flue gas do not affect the accuracy of the system. And completely avoid the high maintenance requirements of precision equipment such as long optical path multiple emission absorption cell.
 
The direct measurement error is small: the direct measurement of ammonia molecular spectrum ensures high accuracy, and there is no conversion rate problem of pretreatment system of indirect analysis technology.
 
The comprehensive operation and maintenance cost is low: the pretreatment system is simple, and the whole process of thermal and wet tracing sampling does not need additional processes such as condensation water removal, reformer and dilution sampling.
