INM-700 in situ NOx/O2 monitor

Capable of measuring NOx and O2 at high temperatures, the INM-700 in situ NOx/O2 monitor uses a zirconium oxide (ZrO2) sensor and non-extractive point measurement. The INM-700 is designed for use in coal-fired boiler applications, such as near-combustion-point readings, or for control of selective catalytic reduction (SCR) systems. The monitor enables operators to use balancing/combustion tuning to identify gas stratification problem areas. With this feature, problems can be corrected to improve burner efficiencies and reduce NOx emissions. The monitor can perform measurements for combustion modification techniques, such as low NOx burners (LNB), over-fire air injection (OFA), gas re-burn systems, and boiler-tuning or combustion-optimization programs used in emissions compliance strategies. The INM-700 offers lower installation and capital costs and faster response time compared to other competing models.
