OR-94-21-3 -- Application of Infrared Thermography to Room Air Temperature Measurements PDF

Introduces a unique technique for rapid measurements of room air temperature distribution at any cross section of interest and shows that infrared thermography can be used with good accuracy for air temperature measurements as well as airflow pattern visualisation. The technique uses a low-thermal- mass, porous, fibreglass screen in conjunction with an infrared camera. The screen is used as a radiation target sheet whose surface temperatures are detected by the infrared camera. Shows that these temperatures are within 1.6degC of the air temperatures.
