Abstract
A laser gas analyzer includes: a laser diode that irradiates a measurement target gas with laser light; a photodiode that receives the laser light that has passed through the measurement target gas; a processor that calculates a concentration of a component contained in the measurement target gas based on an amount of light of the laser light received by the photodiode; and a light emitting diode (LED) that irradiates LED light such that the LED light is received by the photodiode without passing through the measurement target gas.
