Abstract
Abstract A probe cover for an infrared thermometer has a pleated sheath which fits over the thermometer probe and a base, which is engageable with the probe, is attached to the periphery of the sheath to hold the sheath over the probe. The sheath is made of a thin infrared transparent film and is formed with a window which causes minimal attenuation of infrared emission received by the thermometer.
