Abstract

TITRE : DISPOSITIF D’ADMISSION D’AIR POUR INSTRUMENT DE MESURE DE QUALITÉ D’AIR L’invention se rapporte à un dispositif (3) d’admission d’air pour instrument de mesure de qualité d’air. Le dispositif (3) comprend une ouverture périphérique (50), une cavité de prélèvement (55) et deux cavités de ralentissement (52, 53) en communication fluidique avec l’ouverture périphérique (50) et la cavité de prélèvement (55). L’ouverture périphérique (50) et les cavités de ralentissement (52, 53) s’étendent concentriquement autour d’un axe (A1). Figure pour l’abrégé : Figure 3TITLE: AIR INTAKE DEVICE FOR AIR QUALITY MEASURING INSTRUMENT The invention relates to an air intake device (3) for an air quality measuring instrument. The device (3) includes a peripheral opening (50), a sampling cavity (55) and two deceleration cavities (52, 53) in fluid communication with the peripheral opening (50) and the sampling cavity (55). The peripheral opening (50) and the deceleration cavities (52, 53) extend concentrically around an axis (A1). Figure for abstract: Figure 3
