★ High temperature gas detection (optional).


Optional high temperature sampling cooling filter handle or high temperature and high humidity pretreatment system can detect flue gas with a temperature of 1300 degrees. Gas detection at other temperatures can be customized.


★ Three display modes can be switched.


Concentrations of multiple gases are displayed at the same time, the concentration of single-channel gas is displayed in a large font cycle, and the real-time curve is displayed.


★ Graphical display, reflecting the trend of gas concentration change in a period of time in the form of a curve.
