It is used for sampling particulate matter PM2.5 and PM10 in ambient air. It is a high-performance ambient air particulate matter sampler. It meets the standard requirements of "Technical Requirements and Detection Methods for Ambient Air Particulate Matter (PM10 and PM2.5) Sampler" (HJ93-2013). It can realize real-time monitoring of data such as working condition flow, standard condition flow, working condition volume, standard condition volume, ambient temperature, humidity, air pressure and other data, and can be saved, it has the characteristics of reliable operation, simple operation, small size and light weight, and easy installation.

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.
