• The instrument adopts the measurement principle of non dispersive infrared absorption method, with high reliability, strong anti-interference ability and high measurement accuracy.
• The analyzer can simultaneously measure five components (SO2, no, NO2, NOx, O2).
• The oxygen content was measured by electrochemical method.
• The instrument has temperature compensation function, which is suitable for different temperature and humidity environment.
• The instrument has dual range and range ratio of 10:1. It can select high and low range or adopt automatic range switching mode according to different field requirements.
• The flue gas pre processor is equipped to cool, dehumidify and dewater the flue gas before entering the analyzer for detection.
• The function of saving, printing and downloading historical data can copy the data to USB flash disk through USB interface, and automatically generate excel format.

Th-890c portable infrared flue gas analyzer is suitable for the determination of SO2, no, NO2, NOx and other harmful gas concentrations in various boilers, industrial kilns and other fixed pollution sources, and can calculate the emission concentration and emission amount according to the operating parameters; it is suitable for the determination of SO2, no, NO2, NOx and other harmful gas concentration in the atmosphere; it is suitable for the determination of the efficiency of various desulfurization and denitrification equipment; it can also be used for the oxygen content of flue gas Determination of excess air coefficient.
