Abstract
An improved ratio type infrared thermometer utilizes integrating amplifiers for each waveband having the integration time automatically set so that the output voltage utilizes the full range of an analog to digital convertor. The gain and offset of the amplifiers is not ambient temperature dependent so accurate digital representations of the signal for each waveband are provided. The linearized output of each detector is optionally provided so that special or proprietary algorithms for computing the temperature of colored objects can be utilized. A special feature for downloading of updated new programs utilizes a 'programming jumper' and an attenuation warning signal is provided for selected levels of attenuation.
