The Portable Ambient Air Sampler (hereinafter referred to as the sampler) is an essential instrument for capturing particulate matter (TSP, PM10, PM2.5, etc.) and various gaseous components (SO₂, NOx, etc.) in the atmosphere. Developed through extensive consultation with experts and users, this sampler incorporates cutting-edge technologies in computing, sensors, and new materials, ensuring reliable quality, stable performance, and a long service life.
The Portable Environmental Air Sampler employs solution absorption methods to collect various harmful gases from ambient and indoor air, utilizes solid-phase adsorption techniques for capturing volatile organic compounds (VOCs), and applies membrane weighing methods to collect total suspended particulates (TSP), inhalable particulates (PM10 or PM2.5), fluorides, heavy metals, and semi-volatile organic compounds (SVOCs) from ambient air. Suitable for routine and emergency monitoring of gaseous substances and aerosols by environmental protection, health, labor, safety supervision, military, research, and educational departments.
Multi-functional design supports dual constant-temperature/constant-flow atmospheric sampling channels, two low-flow constant-flow sampling channels, and one TSP sampling channel. Features independent control and flexible configuration.
Adjustable particulate sampling flow rate. Compatible with specialized sampling heads for fluoride, heavy metals, SVOCs, and other substances.
Features a 7.0-inch wide-temperature high-brightness color touchscreen display, offering clear visibility in sunlight, an aesthetically pleasing interface, and user-friendly operation.
Equipped with an imported sampling pump, delivering high load capacity, low noise, stable flow rate, and extended service life.
Dual operation modes—button and touch—accommodate diverse user preferences.
Optional built-in rechargeable lithium battery provides over 4 hours of operation per charge.
Automatically measures temperature and atmospheric pressure, calculating standard sampling volume.
Compact and lightweight for easy portability.
Aluminum alloy sampling head resists static adhesion.
Automatically protects data during power outages, resuming sampling upon power restoration.
Dual data output modes: printable or exportable to USB drive.
Superior dustproof and waterproof design ensures reliable operation in rain or snow.
Electromagnetic compatibility design provides strong resistance to interference and radiation.
