This session will discuss the applied theory and recommended practice for making temperature measurements using infrared thermometers. Attendees will divide into three groups for "hands-on" demonstrations with selected instruments.

Participants may bring their own infrared hand thermometers for use during this session. A free calibration check, <1000°F, on a certified blackbody calibration source will be made available for participants’ infrared thermometers.

Avoiding the common pitfalls associated with high temperature reflections from heaters, transmitted radiation through thin sheet, and the challenge of measuring shiny metal molds will be among the topics demonstrated.
