BACKGROUND: Body temperature is a vital parameter in patient assessment. Fever is a common presentation in patients arriving at all health care setups. [1] It is a transient pathological state characterised by a disturbance in the hypothalamus thermoregulation system and, as a result, an increase in the body's temperature above the normal range. Normal

Virtual emissivities of infrared thermometers
Infrared Physics & Technology, 2021Abstract Many testing methods determining thermal emissivity of various materials have been published so far but the methods estimating the virtual emissivity of infrared thermometers themselves are not commonly available and users have to rely on manufacture information.

A new infrared tympanic thermometer
Journal of Anesthesia, 1993We have evaluated a new infrared tympanic thermometer, IT-10, as an intraoperative temperature monitor in patients with or without open abdominal surgery. It determines temperature by measuring infrared radiation given off by a warm object. Temperatures measured with this device were closely correlated with those measured with rectal and bladder ...

Sensitivity of simple infrared thermometers
Journal of Physics E: Scientific Instruments, 1983Simple infrared field thermometers appear to suffer from small internal heat flows which influence the sensor when the instrument is used outdoors. Further research into higher sensitivity of the sensor must be accompanied by increased attention to heat insulation of the instrument and sensor.

Remote-sensing infrared thermometer with radiation balancing
Applied Optics, 2000What is to our knowledge a novel infrared thermometer (IRT) for remote measurement of the temperature rise (-20-100 K) above the variable ambient (270-320 K) of a distant object is described. A radiation-balancing method is successfully extended to the near-ambient temperature range by variation of the temperature of a built-in blackbody, until the ...

Clinical Performance of Infrared Consumer-Grade Thermometers
Journal of Nursing Measurement, 2013Background and Purpose: Technology of ear infrared (IR) thermometers has improved. This study compared a modern ear thermometer to forehead or temporal artery thermometers. Methods: Temperatures were measured with a heated-tip ear thermometer, a temporal artery thermometer, 3 forehead thermometers, and a thermistor-based reference thermometer in ...

A laboratory calibration of infrared thermometers
International Journal of Remote Sensing, 1990Abstract The performance of ‘unchopped’ and ‘chopped’ infrared thermometers is compared under conditions of changing ambient temperature. It is shown that the slow response of the body temperature to changing ambient conditions introduces considerable errors in the output of the early unchopped model. The unchopped sensors can be successfully corrected

A New Generation Of Infrared Thermometers
SPIE Proceedings, 1985Infrared thermometry has a long history of being used for high-temperature applications where no other conventional form of temperature measurement would prove effective or be safe. However, until recent years, instruments for precision measurements in the low tem-peratures were not available.
