Abstract:
A gas concentration measuring device ( 1 ) including a light emitter ( 3 ) and a light receiver ( 4 ) which are disposed so as to be opposed to each other with a hollow tube-like measurement pipe ( 2 ) interposed therebetween. The device ( 1 ) is configured to measure concentration of target gas passing through the measurement pipe ( 2 ) using light applied from the light emitter ( 3 ) transmitted through the inside of the measurement pipe ( 2 ), and received by the light receiver ( 4 ). Purge gas guide pipes ( 11, 13 ) through which purge gas is introduced into optical systems of the light emitter ( 3 ) and the light receiver ( 4 ) are connected to a side wall of the measurement pipe ( 2 ). The measurement pipe ( 2 ) includes a gas entrance portion ( 21 ) having a tapered shape widening from a gas supply port toward a downstream side thereof.

Claim (Index 3):
The gas concentration measuring device according to  claim 2 , wherein the measurement pipe further includes a gas exit portion provided downstream of the measurement portion, and the gas exit portion has a tapered shape narrowing toward a gas discharge port of a downstream end portion of the measurement pipe in the flow direction of the target gas.
