The PES-Gas C6 gas sampler is equipped with a 6-channel DNPH sorbent tube system. Its micro-electromechanical control system precisely regulates the opening and closing of sampling channels, enabling automated sequential sampling across the sorbent tube array. The compact ozone scrubber maintains high ozone removal efficiency without introducing additional airflow resistance. Featuring a modular sorbent tube tray design, it allows users to flexibly replace tubes of different specifications, significantly expanding the device's application scenarios.
The PES-Gas T6 gas sampler employs traditional chemical absorption impingers as independent sampling media across its six channels, with each channel allowing for customizable sampling duration and interval cycles. An precise flow control system ensures accurate air volume measurement, providing a reliable data foundation for pollutant concentration calculations. This unit is capable of collecting samples with hourly time resolution, supporting the offline analysis of various volatile organic compounds (VOCs) and thereby providing technical support for high-precision pollutant source apportion
