FIELD: monitoring and measurement technology; devices for determination of parameters of dust-laden atmosphere; determination of dispersed aerosols.
SUBSTANCE: device is provided with triplets located on plane perpendicular to optical axis; triplets continuously increase with distance. Planes of said triplets consist of red, green and blue strips connected by means of objectives. Aerosol under test is placed between two objectives. Proposed portable device may be used for approximate determination of granulometric composition of aerosol particles.
EFFECT: enhanced efficiency.
