As for the accuracy of IR thermometers... Confectionery partner Barbara and I were making toffee last week and using my IR thermometer. Strangely the batch was beginning to burn but didn't register the required temperature on my thermometer. Barbara brought out her thermometer and it registered much hotter than mine...which would explain the slight burning smell. (The toffee was scrumptious anyway.)
Then Barbara noticed that my battery was signaling 'low'. Aha! So that was the reason. New battery in. Thermometer back in the running...
Have you found that IR thermometers are reasonably accurate (with fresh batteries)? I have been wondering. Yesterday I tested, and both IR and non-IR gave approximately the same reading. Other times they have been too far apart for comfort. I am new to using IR and am still not confident enough in the accuracy. But they certainly are convenient, especially when testing two different mixtures at the same time and when one of them is tempered chocolate (it's difficult to remember that I mustn't dip a regular thermometer into some liquid and then into tempered chocolate).
First low battery/low inaccurate reading for me, so I can't really comment.
