| titleOfInvention | Simple chamber for measurement and pretreatment of formaldehyde or VOC emissions |
| abstract | A simple chamber for measuring and pretreating formaldehyde or VOC emissions, including chamber (1). The chamber (1) is provided with a chamber door (2), an intake port (3), and an exhaust port (4). The outer wall of the chamber (1) is provided with at least one semiconductor cooling chip (5) or liquid temperature control cover (16) that allows cooling and / or heating. A stirring fan (6) is provided inside the chamber (1). The outer wall of the chamber (1) is located in the heat conductive region of the semiconductor cooling chip (5) or is provided with a temperature sensor (7) for measuring the temperature of the liquid temperature control cover (16). A temperature / humidity sensor (17) is mounted inside (1). A filter duct (8) communicating with the inside of the chamber (1) is connected to the outside of the chamber (1). The filter duct (8) is provided with an intake on-off valve (9), an exhaust on-off valve (10), a filter device, and a filter fan (11). The present invention has a simple structure and low cost. It is also possible to provide a constant temperature and / or constant humidity cleaning chamber (1) capable of controlling temperature, relative humidity and background concentration. This provides a stable standard measurement environment for the measurement and avoids the influence of environmental factors or other uncertainties on the measurement results.
