Claims

[Scope of utility model registration request]

(1) In an infrared gas analyzer that continuously quantitatively analyzes the first and second gases to be measured introduced into the first and second measurement cells from the amount of infrared absorption, openings facing each other are a light source block having a completely sealed container having first and second infrared transmitting windows and in which an infrared inert gas is sealed; and a coil-shaped heating element disposed inside the container; a voltage source;
a pulse modulator that pulse-modulates the output from the power source and supplies it to the heating element, and transmits the infrared rays through the first and second infrared transmission windows of the light source block to perform the first and second measurements, respectively. An infrared gas analyzer characterized by irradiating cells with pulsed infrared rays.

(2) The infrared gas analyzer according to claim (1), wherein the heating element is double-wound.

(3) The heating element is made of a tungsten filament.
Infrared gas analyzer described in ).

(4) The infrared gas analyzer according to claim 1 or 2, wherein the heating element is a rhenium-tungsten filament.
