　　2、 Introduction to BY-400 Air Microbial Sampler:

　　The BY-400 intelligent six level sieve impact air microbial sampler can automatically set the environmental air microbial sampling for 6 weeks. It is a product designed by our factory, with two sampling methods: single period sampling and multi period sampling. The sampling flow rate is large, the stability is good, and the power supply adopts AC/DC dual-use type, which is convenient to use. It has a small size and light weight, and can be widely used for monitoring in hygiene and epidemic prevention, biological cleanliness, pharmaceuticals, fermentation industry and other environments, as well as for sampling and research of air microorganisms in relevant research and teaching departments. It provides a basis for evaluating the harm of air environmental microbial pollution and its prevention and control measures.

　　3、 Technical parameters of BY-400 air microbial sampler:

　　The instrument adopts a multifunctional microcontroller control module, a large screen LCD display, Chinese menu, human-machine dialogue mode, and Chinese prompts when human intervention is required. This model is developed by our factory, and the instrument automatically controls the sampling flow rate. It uses a multifunctional controller to control constant current sampling and automatically compensates for flow changes caused by voltage and resistance changes. (Electronic flowmeter), with high sampling accuracy and stable flow rate.
