I have good experience with IR point and shoot thermometers but long term experience with your specific model will lead to best results. My view is they are not precision instruments but give you good ballpark numbers once you know it's strengths ands limitations.

For Ryan, a Variac is extremely useful with a popper. It can give you time and temp. control that is out of reach otherwise. 

I used to use a thermocouple in my popper but have been doing it by sound and smell for the last 5-6 years. I consider it more art than science and prefer to let the process flow over me than try to control the details. It's may not produce anything close to perfect results but I like the variation and look forward to varying tastes with the same beans. Every time I grind up a fresh roast it's like a mini-Christmas morning - I never know exactly what will be in the cup but it's never bad and sometimes fabulous.
