I think you can use a thomermal couple to verify the actual temperature.

Hot air temp 425 C is too high for the some components repair. You should 
check whether the component can bear such high temp, or not.


Thanks and best regards

[RMX:##] [TGAsia] measure the hot air temperature method






Hi,All:
In IPC 7721 and 7711 document just mentioned the hot air temperature  is 
approximately 425℃ and adjust it if necessary ，but it didn’t define the 
test method to get the real  temperature. 
Do you have the relative solutions?
Thanks,
