hi john, i do have infra red ones, i just wanted a wired one that i could put in the oven, let the stat cycle a couple of times and take a reading.
i don’t use the infra red ones for cooker work, just refrigeration.
can you use them through the glass? if not, i would have thought that once you opened the door, you’d lost most of the heat and then the accuracy?
On the fluke it will give an average temp so I just open the door point it at the bottom, both sides and the back to get a reading, I also have a Metrahit 16i with a PTC probe and when I have used both the difference in the readings in negligible.
