LY-3072 Intelligent Dual-channel Flue Gas Sampler Type 18 is a professional stack gas sampling instrument for stationary pollution sources. It adopts solution absorption method to efficiently collect harmful gases such as SO₂ and NOₓ from exhaust gas. The instrument supports dual-channel independent control, real-time monitoring of flue gas temperature, pressure, velocity and flow rate, with stable performance and long running time. It is widely used in environmental protection, third-party testing, industrial and mining enterprises, public health, safety supervision, scientific research and education fields.
Dual-channel flexible sampling design, each channel can be controlled independently, stable flow, high load capacity, ensuring long-term reliable operation.
Simultaneously measure dynamic pressure, static pressure, total pressure, flue gas temperature, velocity, flow rate and standard dry flue gas flow rate.
Supports data storage, query, printing and export, convenient for on-site testing and report output.
Built-in lithium battery supports long-time field operation without external power supply.
Optimized human-machine interface, easy to operate, in line with on-site usage habits.
Fully meets national and industrial standards for flue gas sampling, with high accuracy and good stability.
