QC-2A Double-Air-Channel Air Sampler

Introduction of QC-2A Double-Air-Channel Air Sampler

QC-2A Doubleair channel air sampler is a common instrument for collecting the gas in atmospheric environment and workshop site, widely used in disease prevention, labour safety, safety supervision, atmospheric environment monitoring, Military, scientific research institutes, health monitoring and evaluation of metallurgy, oil chemical industry, health supervision, railway, building materials,etc and can collect all the noxious gases in workplaces The instrument has the advantages of compact structure, stable performance, small volume, light weight, easy to carry which is an ideal one of small portable air sampling instruments in the present, suitable for long time two gases and balance sample collection.
