overview

minuteThe bioaerosol concentrator is based onAnderson impact principle development, microbial aerosol concentrator is divided into two parts, impact chamber and collection chamber. The impact chamber consists of an impact plate and a receiving plate.

This product complies withStandard《GB/T 18204.5-2013 Public Place Hygiene Inspection Methods Part 5: Central Air Conditioning and Ventilation Systems "and the hygiene industry standard" WS 394-2012 Hygiene Specification for Central Air Conditioning and Ventilation Systems in Public Places "require the collection of central air conditioning supply air and the detection of Legionella pneumophila in it. Large collection flow rate enables the required particles to be concentrated into the sampler in a short period of time, avoiding the loss of biological activity caused by long-term sampling and improving the practicality of the sampler on site.
