1. Product introduction
The JCH-120S intelligent air fluoride sampler (hereinafter referred to as the sampler) is an essential sampler suitable for collecting heavy metal particles (TSP) and fluoride samples in the atmosphere. The instrument adopts G new technology in the fields of sensors, new materials, etc., with reliable quality, stable performance and long service life. Membrane weighing method is used to capture heavy metal particles (TSP) in the ambient atmosphere and fluoride in the air. It can be used for routine and emergency monitoring of gaseous substances and aerosols in environmental protection, health, labor, safety supervision, military, scientific research, education and other departments.
