INLINE CONCENTRATION MEASUREMENT DEVICE
First Claim
1. An inline concentration measurement device, comprising:
- a measurement cell main body in which a gas flow path is formed;
a light incident part having a window member and being connected to the measurement cell main body; and
a light receiving part having a window member and being connected to the measurement cell main body,wherein the gas flow path includes a gas flow path part for an optical path extending straight between the window member of the light incident part and the window member of the light receiving part to provide the optical path, a first communication part making a gas inlet formed in the measurement cell main body communicate with the gas flow path part for the optical path, and a second communication part making a gas outlet formed in the measurement cell main body communicate with the gas flow path part for the optical path, and wherein the first communication part obliquely extends from the gas inlet towards the window member of the light incident part.
