More Information
Summary:The utility model discloses a precise constant-temperature infrared cell device, which is characterized in that a heat insulating material layer (3) is covered on the inner chamber of a box body (2), and a gas stirring and heating device is mounted at the bottom of the inner chamber of the box body (2); a tested gas induction pipeline (1) is mounted in the middle of the box body (2), and an infrared gas detector (4) is connected to the end of the tested gas induction pipeline (1); a tested gas outlet pipeline (7) is mounted in the middle of the box body (2), and another infrared gas detector (4) is connected to the end of the tested gas outlet pipeline (7); and a temperature sensor (8) is arranged on the lateral surface of the box body (2). The utility model aims to provide the precise constant-temperature infrared cell device less susceptible to external environment temperature and small in measuring error.
