The RT-CS2 is a portable two-filter membrane PM2.5 sampler, which can place two filter membranes at the same time. The sampling time of each filter membrane is optional in 1-99 hours. After sampling, the system automatically replaces another filter membrane, which meets the HJ93-2013 of national environmental protection standards. The sampler not only meets the portability requirement of a single-filter membrane sampler, but also solves the problem of fixed time membrane replacement of an automatic single-filter membrane sampler. It is an ideal choice for mobile quality control and portable quality control.

RT-CS6 sampler is a high-performance multi-filter membrane ambient air particulate matter PM2.5 sampler. The 6 filter membranes can be automatically sampled by membrane change, and the collected particles can be stored at low temperature, effectively preventing the loss of volatile organic compounds in the particles. This instrument adopts the unique transmission design, which effectively improves the reliability of the instrument. It is a small size, light weight and stable operation of the particulate matter sampler. It can meet the sampling requirements of ambient air particle mass concentration, anions and cations, carbon, elements and organic matter at the same time.

The RT-CS20 sampler is a high-performance multi-filter membrane ambient air particulate matter PM2.5 sampler. The 20 filter membranes can be automatically sampled by membrane change, and the collected particles can be stored at low temperature, effectively preventing the loss of volatile organic compounds in the particles. This instrument adopts the unique transmission design, which effectively improves the reliability of the instrument and reduces the volume and weight of the instrument. It is a small, light and stable particulate matter sampler. It can meet the sampling requirements of ambient air particle mass concentration, anions and cations, carbon, elements and organic matter at the same time.

RT-AP4 four-channel ambient air particulate matter sampler adopts homologous secondary cutting technology to realize simultaneous sampling of various particulate matter four-filter membranes. The four sampling filter membranes can be any one or more combinations of TSP, PM10, PM5, PM2.5 and PM1. At the same time, four suction pumps and four flow sensors are used to realize flow sharing control. The sampler has the characteristics of reliable operation, simple operation, and simultaneous collection of multi-component four filter membranes, which is an ideal choice for source analysis sampling.
