The LY-3012H-D intelligent stack dust tester is a high-performance multi-functional environmental monitoring instrument designed for industrial facility managers, environmental compliance departments and third-party testing organizations. Adopting the Pitot tube parallel isokinetic sampling method for particulate matter collection and filtration weighing method for dust mass quantification, this tester also supports qualitative and quantitative analysis of flue gas components via potentiostatic electrolysis, UV differential or non-dispersive infrared technologies. It is widely used for accurate measurement of particulate matter emission concentration, converted concentration, total emissions and dust removal efficiency from various stationary pollution sources, with additional capabilities to evaluate desulfurization equipment performance.
The tester utilizes the Pitot tube parallel isochronous isokinetic sampling method, ensuring highly representative collection of particulate matter from stationary source exhaust. A high-precision electronic flowmeter with real-time temperature and pressure compensation guarantees accurate flow control, delivering reliable data for ultra-low concentration particulate matter monitoring in strict industrial emission scenarios.
It supports real-time synchronous monitoring of full-process operational parameters, including flue gas dynamic pressure, static pressure, temperature, flow velocity, standard dry flow rate, oxygen content, excess air coefficient and flue gas moisture content. This eliminates the need for multiple separate instruments, drastically improving on-site testing efficiency for industrial compliance teams.
The instrument supports optional sensor configuration based on on-site requirements, enabling simultaneous measurement of multiple flue gas components (SO₂, NO, NO₂, CO, CO₂) with multiple sensing principles. It is compatible with various sampling tubes to achieve dust sampling, flue gas analysis, flue gas sampling and direct dust reading functions, adapting to diverse industrial working conditions.
Equipped with a high-brightness display optimized for harsh field environments, the tester features an intuitive user interface for clear data presentation. It has built-in full self-diagnostic functionality for real-time instrument performance testing and fault alarms, simplifying daily maintenance. It supports dual power supply via an integrated lithium battery pack or AC power adapter, suitable for long-term field operation.
The LY-3012H-D stack dust tester fully complies with national and international stationary source particulate matter sampling and monitoring standards, including China’s stationary pollution source particulate matter emission testing specifications, relevant USEPA sampling methods and EN industrial dust monitoring standards. It meets the strict requirements of environmental law enforcement inspections, enterprise emission self-monitoring and third-party laboratory testing, ensuring full compliance with global industrial environmental regulations.
