Which one should be used as the standard: the exhaust gas temperature at the chimney inlet or the online measured exhaust gas temperature?

The exhaust gas temperature at the entrance of the large chimney is 235°C, with a suction force of 350 PA; the exhaust gas parameters measured online show 108°C. Is there something wrong with this value? Standard temperature: 1280°C. Thank you.
Measure the chimney suction, using the temperature at the base of the chimney as a reference; the temperature monitored online is independent of the online levels of SO2 and NOX
Thank you for the answer, but I would like to ask whether it is appropriate to determine the temperature of chimney exhaust gases at the base of the chimney or through online monitoring?
There are monitoring points available for reference; it should be based on the heating regime of the coke oven, of course, at the root area； The temperature at the online monitoring points is, of course, used for data conversion!
The temperature at the base of the chimney should be no less than 250 degrees Celsius; 235 is a bit low
It’s normal to burn blast furnace gas! !
