Dear Researchers,

I was conducting an experiment using a hot air gun which has three variable speeds and a wide range of temperature(50-530 degC) for thermal flow sensing applications. I aim to study the effect of hot air flow at higher temperatures due to Joule heating. However, I'm quite skeptical that if I can use a simple hot air gun? Because, the actual temperature inside the channel changes everytime for different flow rate. However, I require a fixed temperature (say 100 degC) and use different flow velocities. Can anyone suggest some solutions? Thank you.
