ZR-3920G high negative pressure ambient air particulate matter sampler

ZR-3920G high negative pressure ambient air particulate matter sampler

Product Introduction

The ZR-3920G high negative pressure ambient air particulate sampler is specifically designed for sampling air fluorides, heavy metals, and SVOCs, and can also collect atmospheric particulate matter (TSP, PM10, PM2.5). It can be used for routine aerosol monitoring by departments such as environmental protection, health, labor, safety supervision, military, scientific research, and education.

Technical Features

The whole machine has excellent waterproof, dustproof, and anti-collision performance, and can work normally in rainy, snowy, dusty, and severely hazy weather.
VOC sampling tank that meets the requirements of glass fiber filter membrane and PUF adsorption resin; Acetate nitrocellulose membrane (fluoride); Perchloroethylene film (heavy metal)
Sampling requirements for PTFE (polytetrafluoroethylene) and quartz filter membranes.
Adopting a 5-inch color touch screen, the content is more intuitive and the operation is easier.
Choosing different sampling heads can achieve the collection of TSP/PMIO/PM2.5/fluoride/air heavy metals/SVOC/SVOCs; The air fluoride sampling head is standard.
Adopting imported high flow, high negative pressure, long-life (uninterrupted operation time>20000 hours) brushless sampling pump, with a flow rate of 50L/min and a load capacity>20kPa.
The imported sampling pump controller is equipped with air path blockage and low flow protection functions.
● Supports USB data export, built-in large capacity data storage, and instant data storage function.
There are two file formats for archiving: TXT and CSV; Optional printing function module

Adopting high-precision, corrosion-resistant, and high humidity resistant electronic flow meters ensures high reliability and high sampling volume accuracy.
Adopting imported pressure sensors.
Automatically measure atmospheric pressure and temperature, and automatically calculate standard volume.
During the sampling process, if there is an interruption in power data, automatic protection will be provided, and sampling will continue after a power call is received.
● Can perform timed sampling, interval sampling, and 24-hour continuous sampling.
