TQ-2000 Intelligent Four-Airway SystemAtmospheric SamplerThis is an atmospheric sampler launched by our company. The instrument uses a single-chip microcomputer as its intelligent control central processing unit, enhancing its applicability. It is widely used in atmospheric environmental monitoring and indoor air quality detection.

The intelligent operation platform is built on a smart, refined internal management system with menu settings, capable of remembering the last sampling time, continuous and intermittent sampling, intelligent power management, real-time battery display, charging indicators, and an efficient imported coreless cup motor drive. Featuring a large LCD screen, automatic shutdown after no operation, and more, it is a practical atmospheric sampler available in the market.
