摘要: The measurement sensitivity is improved by suppressing the surrounding temperature influence as much as possible, while realizing scale reduction, and by enlarging the detection signal, while reducing the production errors in enclosing a reference gas. Provided is a thermal conductivity sensor that detects thermal conductivity of a sample gas by using a Wheatstone Bridge circuit constructed in such a manner that measurement resistors that are brought into contact with the sample gas are disposed on a first side, and reference resistors that are brought into contact with a reference gas are disposed on a second side, and comparing the potential difference between connection points of the reference resistors and the measurement resistors. The measurement resistors disposed on the first side are assembled in one measurement space, and the reference resistors disposed on the second side are assembled in one reference space.

摘要: A gas analyzer has a simple composition and can measure multi-components at a high accuracy. A plurality of measuring cells, including a case where the cells are different in length from each other, communicate sequentially with each other through a communication part to form a single gas path.

摘要: A gas concentration measuring apparatus for measuring a concentration of a measurement target substance contained in a sample gas includes a light source unit in which a light source is arranged, and a sensor unit that is arranged on an optical path of the light source. The sensor unit includes a concentration measuring sensor configured to receive light from the light source after the light has passed through a sample cell unit and measure a concentration of the measurement target substance. The apparatus further includes an introducing device configured to introduce the sample gas to a vicinity of concentration measuring sensor. Therefore, a vicinity of the concentration measuring sensor is filled with an atmosphere of the sample gas so that a concentration of a measurement target substance contained in the sample gas is measured stably and accurately regardless of fluctuations in an ambient atmosphere of a measuring environment.
