Device for measuring catalytic characteristic of material

The invention relates to the field of catalytic characteristic measurement, and discloses a material catalytic characteristic measuring device which comprises an outer shell. The insulating sleeve is connected in the outer shell; the number of the installation heads is two, and the two installation heads are both connected into the insulation sleeve; the number of the sensitive pieces is two, the two sensitive pieces are connected to the ends of the two mounting heads respectively, and the two sensitive pieces are flush with one end of the insulating sleeve and one end of the outer shell; and the number of the thermocouples is two, and the two thermocouples are respectively inserted into the two mounting heads and are respectively connected to the two sensitive pieces. The limitation that an existing electron density number measuring device is only suitable for a ground static field environment is overcome, and the device adapts to the catalytic effect of a structure surface material in a high-Mach and high-t
