 Microcomputer constant current system controlLCD display system, menu settings, AC/DC dual voltage, optional with lithium battery power supply

TQ-2000 Smart Four-Air PathAtmospheric SamplerThis is an atmospheric sampler launched by our company. The instrument utilizes a microcontroller as the intelligent control central processing unit, enhancing its applicability. It is widely used in atmospheric environmental monitoring and indoor air quality detection.

This intelligent operation platform is built on a smart, refined internal management system with menu settings, capable of remembering the last sampling time, offering continuous and intermittent sampling options, intelligent power management, real-time power display, charging indicator, and an efficient imported hollow-core cup motor drive. With a large LCD display, features like automatic shutdown after a period of inactivity, and more, it is a practical atmospheric sampler available in the market.
