This instrument samples VOCs (volatile organic compounds) in the waste gas of stationary pollution sources by solid-phase adsorption. It can also perform solution-absorption sampling of polluting gas components such as SO₂ and NOₓ in stationary source emissions, and can serve as a flue gas pretreatment unit alongside a flue gas analyzer for concentration measurement. It is widely used in environmental protection, testing companies, industrial and mining enterprises, public health, labor and work safety supervision, the military, scientific research, education and other fields.
The LY-3038C All-In-One Flue Gas VOCs Sampler is a portable, multi-functional sampling device for monitoring the exhaust gas of fixed pollution sources. It supports solid-phase adsorption VOCs sampling and solution absorption sampling for SO₂, NOₓ and other gaseous pollutants, and can work as a flue gas pretreatment unit for flue gas analyzers. With stable flow control, real-time parameter measurement, large-capacity data storage and a compact handheld design, it delivers safe, accurate and efficient on-site sampling for environmental protection, industrial inspection, safety supervision and laboratory testing.
Three-in-One Multi-Mode Sampling :
VOCs sampling, flue gas sampling and flue gas pretreatment are combined in one device. It supports solid-phase adsorption tube sampling for volatile organic compounds and solution absorption sampling for conventional gaseous pollutants, meeting a wide range of fixed pollution source sampling requirements.
Stable & High-Precision Sampling Performance :
An electronic flow meter keeps the flow steady and accurate, and a high-precision diaphragm pump provides strong load capacity and a long service life. The unit automatically measures ambient temperature, atmospheric pressure, gauge pressure and gauge temperature, and converts and displays standard volume and reference volume in real time for reliable sampling data.
Intelligent Data Management & Portable Operation :
Large built-in storage supports saving, reviewing, exporting and printing sampling data. The compact, lightweight structure is easy to carry and comfortable to hold for field and on-site use, and automatic parameter monitoring with intuitive operation greatly improves working efficiency on site.
The LY-3038C flue gas VOCs sampling system is designed and manufactured in line with national and industry standards for stationary pollution source monitoring:
