Product Description

The PM2.5 monitor is a monitor for detecting the quality of particles in the atmosphere that are less than or equal to 2.5μm of fine particulate matter. Compared with the coarser atmospheric particles, PM2.5 particles have small diameter, large area and strong activity, which are easily associated with toxic and harmful substances (e.g., heavy metals and microorganisms), and long residence time in the atmosphere, conveying distance, and thus the impact on human health and environmental quality of the atmosphere more. This instrument uses the principle of laser scattering. Let the scattering laser irradiation suspended particles in the air. At the same time, to collect scattered light at a particular point of view, get the scattering intensity versus time curve. Then the equivalent particle size of particles and the number of particles of different sizes in unit volume are obtained.
 

Features:

• Digital LED display screen shows the testing results, easy and clear to read.
• Accurate to detect PM2.5 in air with advanced laser detection sensor technology in real time.
• Easy to carry with the super mini pocket size and light weight - monitor air quality wherever you are.
• Built-in large capacity battery, long standby time. Continuous work over 4.5 hours with USB cable charging function.
• Alarm function: when the detected result over the setting value, the result will blink in red to alarm. (alarm setting: short press SET to set he alarm, display shows the current alarm value.)
• Auto power off: it cannot be power off automatically 30 minutes without any operation.
• Temperature/humidity meter: it also can measure indoor/outdoor temperature and humidity.
• Application: suitable to use at home, office, in the car, outdoor and other environmental testing.
