ZR-3920S four-way ambient air particulate comprehensive sampler Introduction
ZR-3920S four-way ambient air particulate comprehensive sampler (four-way normal temperature) using filter weighing method to capture total suspended particulates (TSP) and inhalable particles (PM10, PM2.5) in the ambient atmosphere, using solution absorption The method collects various harmful gases in the ambient atmosphere and indoor air. It can be used for environmental monitoring, sanitation, labor, safety supervision, military, scientific research, education and other departments for routine aerosol monitoring. Features
Imported large-flow brushless sampling pump with strong load capacity;
Four-channel constant current sampling, can work at the same time or can be controlled separately;
Air circuit blockage and low flow protection;
Power-down protection function, automatic memory power-down time, power-off and then call to continue sampling;
With real-time clock, support timing and interval sampling settings;
Large screen color highlighting touch screen;
USB data export function;
Optional portable Bluetooth printer (with built-in lithium battery). Technical parameters
