SUMMARY
Theory and practice of a sensitive infrared surface thermometer are dealt with. Several problems arising in the field use of this simple instrument are discussed and explained in detail. It is concluded that with the indicated precautions the instrument is operating at optimum reliability and accuracy. However, further increase in sensitivity will not yield higher accuracy.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
