Abstract
An infrared sensor 20 is held in a housing 10 by a sensor holder 28 made of synthetic resin. A waveguide 30 for guiding infrared radiation, which is emitted from a target, to the infrared sensor 20 is supported by waveguide holders 31, 32 made of synthetic resin (or metal). An air layer (insulative layer, gap) 34 resides between an inner end (terminal end) 30b of the waveguide 30 and the infrared sensor 20. A probe 40 made of synthetic resin surrounding an externally protruding portion of the waveguide 30 is provided. An air layer (insulating layer, gap) 33 resides between the tip of the probe 40 and a tip (outer end) 30a of the waveguide 30. The tip of the waveguide 30 is covered by a cap 50.
Claims2
An infrared thermometer comprising:
- infrared measurement means for measuring temperature of a target based upon an output of an infrared sensor;
- temperature measurement means for measuring temperature within the infrared thermometer;
- means for determining whether the temperature measured by said temperature measurement means lies within a measurable temperature range of said infrared measurement means;
- means for estimating waiting time that would be needed for the temperature measured by said temperature measurement means to fall within the measurable temperature range when said determination means has determined that the measured temperature does not lie within the measurable temperature range;
- and
- means for giving notification of the waiting time that has been estimated by said estimation means.
