1. The heating automatic adjustment unit is adopted, and the heating temperature is maintained to about 150°C to avoid condensation.

2. The probe filter element adopts 2um pore nickel-titanium alloy, which can effectively remove the smoke and dust in the sample gas.

3. The probe has a back-blowing function, which can realize automatic back-blowing through the control system to overcome the blocking problem to the greatest extent and reduce the amount of maintenance.

4. The parts and flanges in contact with the flue gas are made of 304 stainless steel to avoid material corrosion and measurement errors caused by long-term use.

5. The main body of the probe is painted with paint.
