FIELD: air control systems.
SUBSTANCE: invention relates to air control systems using chemical methods, primarily using indicator tubes filled with a chemical indicator, placed in a common housing with an air flow exciter, and can be used in air studies at workplaces, while monitoring emissions of chemical production in the environment. Miniaspirator for determining various analytes in air comprises a housing with detachable cover, overall dimensions of not more than 100×70×50 mm and weight of not more than 0.3 kg, in which there are functional units: a vacuum micropump, a power supply unit, an air pumping time setting device and a voltage stabilizer.
EFFECT: high efficiency with simultaneous expansion of the range of technical means for determining various analytes in air.
