1. the measuring method of an infrared thermometer is characterized in that:

  • Measuring method is;

    (1). measure the series standard temperature value T of testee by the temperature standard surveying instrument i, adopt the infrared thermometer that is under the align mode to measure testee simultaneously corresponding to above-mentioned standard series temperature value T iSeries of heat radiation signal voltage U i(T i), wherein above-mentioned i=1.2.3. ... N is input to PC with the data that record and carries out data processing, and the physical model that this PC data processing is adopted is;

    For service band is the infrared thermometer of arrowband, and the physical model of employing is;

    U(T)=

    Ae B/TMake index return, obtain the concrete numerical value of computing parameter A, B;

    For service band is the infrared thermometer in broadband, and the physical model of employing is;

    U(T)=

    f(A、

    B、

    C、

    D、

    T)Data are imported this physical model and made least square fitting, obtain the concrete numerical value of computing parameter A, B, C, D;

    (2). the arrowband of being tried to achieve or the computing parameter in broadband are input in the infrared thermometer system, promptly finish the calibration of arrowband or wideband operation wave band infrared thermometer;

    (3). use infrared thermometer that the testee that enters the thermometric state is implemented thermometric, to receive the infrared energy value of testee;

    (4). carry out calculation process by the microcomputer in the infrared thermometer system by physical model, can obtain the temperature value of testee;

    (5). temperature value is shown by display.
