Hi Lewis,

All hot air gun have their sensors. Generally, the probe is located in the center of hot air outlet.

In 7711/21, the temperature is not mandatory. There is a way to confirm the temperature with a piece of paper. You can find it in followed steps.

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,
