Air Quality Meter
Keywords: PM2.5 meter, AMF079 particle counter, air quality meter, PM2.5 monitor, particulate counter
PM2.5 air quality meter using laser technology to measure inhalable particle concentration, with additional air temperature and humidity measurement.
1. Measures PM2.5 concentration with laser technology, very sensitive
2. Sampling method: pumping type with laser diode light source
3. Grain size channels: 0.3 μm, 2.5 μm, 10 μm
4. Stores 999 sets of data
5. Automatic power off after 2 minutes of no key operation
6. Measures air temperature and humidity
