2、 Performance characteristics

1. Small size, light weight, and easy to carry.

2. Directly test NO and NO2 in flue gas without the need for molybdenum conversion.

3. Directly measure O2, Ts, Pt, Pd, Qsd in flue gas.

4. The SO2/NO/NO2/NH3 test adopts differential absorption algorithm, which has high measurement accuracy.

5. Pre sampling tube with dust powder metallurgy filter to reduce the impact of dust on measurement results.

6. Preheat on-site for 10 minutes, with fast measurement speed and high efficiency, reducing on-site work time.

7. The sampling tube is equipped with dual Peltier refrigeration and a sulfite decomposer to reduce the loss of SO2 and NO2 dissolution.

8. Dove Prisms folded optical path design for gas chamber detection, with long optical path, high gas resolution, and high detection limit.

9. Real time display of monitoring data minute average value, dual USB interface, can export monitoring data, especially suitable for CEMS comparative acceptance calibration.

10. Specially selected high negative pressure high flow flue gas and smoke sampling pump, with flue gas sampling reflux design, to solve the problem of insufficient suction power in high negative pressure flue gas ducts.

11. The monitoring projects for H2S, CS2, CH3SCH3, C6H6, CH2O, and COS can be expanded without the need for additional hardware, reducing procurement costs.

12. Mold based optical path design improves instrument stability and reduces the impact of environmental temperature changes on monitoring results.

13. Two different lengths of docking heating sampling tubes can be optionally selected, suitable for smoke testing behind different tube walls.

14. A 120GB solid-state drive and a specially designed sampling pump can achieve fixed unmanned 24-hour monitoring.

15. Sliding multi-layer conical rubber plug sleeve, suitable for different sizes of flues and sampling holes of different diameters.

16. Compared with traditional electrochemical sensors, there is no need for calibration every time, greatly reducing testing costs.

17. Embedded single board computer, Windows 7 operating system, dynamic display of gas absorption curve.

18. Large scale database communication software that can archive monitoring data from each year for future reference.

19. Set automatic parameter memory, automatic fault protection, and machine parameter software calibration.
