2、 Purpose:Intelligent small flow particulate matter sampler for ambient air 16.67

This instrument is used to collect inhalable particulate matter in the ambient airInstruments for samples of PM10 or fine particulate matter (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.

3、 Performance characteristics

Unique system design for collecting inhalable particulate matter in the atmosphere(PM10) or fine particulate matter (PM2.5) samples

Automatic control of sampling flow rate: using electronic flowmeter, microcomputer system detects sampling flow rate, and automatically compensates for flow rate changes caused by voltage fluctuations, resistance, and temperature changes

Automatically calculate the cumulative sampling volume and convert the standard sampling volume based on air pressure and temperature

During the sampling process, power outages automatically save the number of jobs According to reports, sampling can be restored after a call

Precision core pump, corrosion-resistant, ultra-low noise, maintenance free continuous operation, adaptable to various working conditions, with overload protection function

High quality dust filter screen, achieving efficient filtration function, protecting the sampling pump and gas path

AC/DC dual-use, built-in lithium battery

Can achieve immediate sampling, timed sampling, and equidistant sampling

Wide temperature and high brightness display screen, suitable for high-altitude regions, with a popular software display interface, achieving good human-computer interaction

Sampling data can be stored and printed, making it easy to grasp real-time data

The deviation between the sampling flow rate of the instrument and the set flow rate exceeds± 10%, and if the duration exceeds 60 seconds, the instrument will automatically stop sampling and record this condition

Can provide users with the current date and time at any time for easy operation

Intelligent software calibration function

The sampling head is made of aluminum alloy material and has anti-static adsorption

Modular design, reliable rain and snow protection function
