For those who own a thermometer, is the temp displayed on pid controller close from those measured on coil or injector ceramic? I setup my controller at 520F, but measurement on the coil range from 400 to 450 and the ceramic and ss screen, even after a prolonged heating time and usage is in the 300 range. I know that the temp on the controller is an approximation as it's a cheap combo (sz crossing, but it works well) and what really matters is the temp of the rubies and of air travelling through weed (and on that I found my sweet spot), but I wanted to know if readings are so different in your setups too.
P.S. I realized while writing that maybe my thermometer might be wrong too, I will have to test it idependently once at home
