Portable AC/DC dual-purpose atmospheric sampler

1. Product Overview

Yun TangPortable AC/DC dual-purpose atmospheric samplerSampling is an instrument used to capture particulate matter (TSP, PM10, PM2.5, etc.) and various gas components (SO2, NOx, etc.) samples in the atmosphere. The development process of this sampler extensively solicited opinions from experts and users, and applied high-tech in current fields such as computers, sensors, and new materials. It has reliable quality, stable performance, and long service life.

2. Scope of application

Yun TangPortable AC/DC dual-purpose atmospheric samplerUsing solution absorption method to collect various harmful gases in the ambient atmosphere and indoor air; The filter membrane weighing method is used to capture total suspended particles (TSP) and inhalable particles (PM10) or (PM2.5), fluoride, heavy metals, SVOC, etc. in the ambient atmosphere. It can be used for routine and emergency monitoring of gaseous substances and aerosols by departments such as environmental protection, health, labor, safety supervision, military, scientific research, and education.
