Thermography is the science of detecting and measuring variations in heat e
mitted by an object and transforming them into visible images. It is a rapi
dly developing technology for diagnosis and nondestructive testing in many
applications. This article will illustrate applications where thermography
can be used in the heating, ventilating, and airconditioning arena. Finally
, the article will suggest issues to consider when establishing an IR therm
ography program or when contracting with others to perform the service.
