ZR-3500 Dual air sampler constant current

ZR-3500 type dual air sampler (constant current type) Introduction ZR-3500 type dual air sampler (constant current type) can simultaneously capture two gases or parallel samples for toxic substances in air monitoring and analysis . The instrument can be widely used in environmental protection, health care, food industry, fermentation industry, pharmaceutical industry, agricultural, industrial and mining enterprises, labor health and other related research department. Executive Standard HJ / T 375-2007 "ambient air samplers technical requirements and test methods" JJG 956-2000 "air sampler" technical characteristics of high-performance subwoofer diaphragm, long service life; AC-DC dual-use, built-in high-energy lithium batteries ; Double Air Road sampling, which can work individually controlled; electronic meter, constant sampling, flow control and high precision; dot matrix LCD display, Chinese menu operation; high-capacity data storage, query; exporting USB data; sampling process and then calls automatically restore power outages sampling; built-in clock chip, enabling timing interval sampling and other functions.
