Just be aware that those point and shoot type IR thermometers are less accurate at further distances. Try to get as close a possible to the surface you want to measure. I have one of the laser type ones and at 4 feet it reads almost 20 degrees cooler than at 4 inches. Of course that was of very hot temperatures. When dealing with lower temps that we are used to dealing with the difference is less pronounced but still can be several degrees off.
