<p><P>PROBLEM TO BE SOLVED: To provide a laser-type gas analyzer, capable of determining normalities or abnormalities in light-emitting and receiving sections, using a simple structure. <P>SOLUTION: In the laser type gas analyzer, a calibration curve is prepared that expresses a receiving light quantity at the light-receiving part versus a light-emitting quantity of laser light irradiated from the light-emitting part, a light source part and the light-receiving part are determined to be normal, when a fluctuation rate of inclination of the calibration curve from a standard value lies within a predetermined range and a maximum value of the calibration curve is larger than a predetermined threshold, and other cases are determined as being abnormal. <P>COPYRIGHT: (C)2011,JPO&INPIT</p> |
