A two-way display infrared thermometer comprises a main body. An infrared wave-collecting device is disposed at the front end in the main body. A sensor is disposed at the bottom of the infrared wave-collecting device. A liquid crystal display is disposed on the surface of the main body to display the temperature. A direction detection device is disposed in the main body to detect the horizontal state of the main body so as to control the display direction of the liquid crystal display. A mount is disposed on the main body so that the main body can be supported and adjust the angle of measurement. A direction-switching device is disposed on the main body for manually switching the display direction of the liquid crystal display. Thereby, the infrared thermometer can straightly display the measured temperature for quick reading of the temperature value regardless of standing upright or upside down.

Two-way display infrared thermometer

An absolute radiation thermometer capable of evaluating the absolute value of infrared radiation power emitted from a target and received by a radiation sensor by means of electrical calibration, and calculating the temperature of the target basing on the responsive signal generated in the radiation sensor. To solve 'Microphonic' problem, two identical sensors connected in parallel with the polarized orientations of their pyroelectric layers being in opposite directions so as to cancel the piezoelectric signals generated in the two sensors are used. Further, by using a floating power supply, which is isolated from the system power supply of the thermometer, for performing electrical heating, power supply noise can be greatly reduced.

Absolute radiation thermometer

A waveguide for tympanic thermometer formed by an elongate hollow member having substantially ellipsoidal shape truncated at both ends along its major axis direction. The waveguide is interposed between a tympanic membrane of which the temperature is to be measured and an infrared radiation sensor so as to guide the infrared radiation from the tympanic membrane to the sensor. Alternatively, the waveguide may also be a hollow member including an end portion having a gradually reduced inner diameter toward the side of sensor. The gradually reduced end portion is preferably of a truncated half ellipsoidal shape having a length between about 1/10 to about 1/3 of the distance from the sensor to the distal end of the waveguide.
