LY‑2050 is a multi‑functional thermostatic environmental air comprehensive sampling device. It uses the filter membrane weighing method to collect total suspended particulate (TSP) and inhalable particulate matter (PM10), with optional PM2.5 monitoring. It adopts the solution absorption method to capture gaseous pollutants such as SO₂ and NOₓ in ambient and indoor air, and also supports VOC sampling via solid‑phase adsorption tube. Equipped with an integrated constant‑temperature incubator and multi‑channel independent control system, it is widely used in environmental protection, public health, occupational safety, scientific research and education for routine and emergency air monitoring.
Adopts five independent gas sampling paths, each with adjustable flow and special constant‑flow control, ensuring stable and accurate sampling.
Works as a 4‑channel ambient air sampler and a particulate sampler (TSP/PM10/PM2.5 optional) at the same time, realizing one‑machine multi‑purpose.
Built‑in constant‑temperature chamber can hold four absorption bottles, with adjustable temperature control to ensure constant‑temperature sampling and improve collection efficiency.
Equipped with high‑precision corrosion‑resistant electronic flowmeter for automatic flow control and real‑time parameter tracking.
Adopts high‑performance core pump with ultra‑low noise, corrosion resistance, overload protection and maintenance‑free long‑term operation.
Built‑in lithium battery supports AC/DC dual power supply; large data storage, query, print and USB export functions.
Automatically measures atmospheric pressure, ambient temperature and other parameters to ensure traceable sampling data.
Supports self‑inspection, fault alarm, timing, positioning, anti‑counterfeiting printing and log recording, with information system docking interface.
