ZR-3920 type ambient air particulate comprehensive sampler Introduction
ZR-3920 type ambient air particulate comprehensive sampler (A section, double heating; B section, double channel constant temperature; E section, constant temperature fluoride; F section, heating fluoride), using filter weighing method to capture ambient air The particulate matter (TSP, PM10, PM.2.5) is collected by the solution absorption method to collect 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.
Feature
The whole machine is excellent in waterproof, dustproof and anti-collision performance, which can guarantee the normal work of rain, snow, dust and heavy weather.
With 5-inch color HD LCD touch screen, the content is more intuitive and easy to operate;
The particle sampling pump adopts imported large flow, high negative pressure and long life brushless sampling pump. When the flow rate is 100L/min, the load capacity is >9kPa, and when the rated load is 80%, the uninterrupted running time is >20,000 hours;
Adopting imported sampling pump, the controller has air circuit blocking and low flow protection;
The toxic and harmful gas sampling pump uses two sets of imported high performance subwoofer sampling pumps;
It has three-way simultaneous sampling function, which can collect particles and toxic and harmful gases in the air at the same time, and the sampling flow rate and sampling time are separately controlled;
Constant current sampling, constant temperature sampling (constant temperature type proprietary), timing sampling, interval sampling, 24-hour continuous sampling;
High accuracy, corrosion resistance and high humidity electronic flowmeter ensure high stability and high sampling volume accuracy;
The constant temperature box (constant temperature type) adopts semiconductor constant temperature technology, the heating and cooling temperature can be controlled separately, the drying cylinder and the absorption bottle are built in the incubator to ensure stable temperature performance;
Support USB data export, built-in large-capacity data storage, with instantaneous data storage;
The archive file format is available in TXT and CSV formats;
Ambient atmospheric pressure and temperature, measurable input;
Imported pressure sensor, maintenance-free calibration;
The sampling process interrupts the automatic protection of the electrical data, and continues to sample after the call;
Optional portable Bluetooth printer. (Built-in lithium battery)
