ZR-3500S four-way atmospheric sampler Introduction
ZR-3500S four-way atmospheric sampler (B type, two-way heating two-way constant temperature; C section, four-way constant temperature) can simultaneously collect four kinds of gas or two sets of parallel samples at constant temperature and constant current, suitable for monitoring toxic substances in the air. And analysis. The instrument can be widely used in environmental protection, medical and health, food industry, fermentation industry, pharmaceutical industry, agriculture and animal husbandry, industrial and mining enterprises, labor health and other related research departments.
