Brief introduction: The instrument using the method of optical detecting dust concentration in the air, when the dust particles in air flow through the sensor, Dust particles on the beam of light scattering, receiving module according to the detected signal strength, to determine the concentration of dust; Through the judgment of the output pulse width to distinguish the size of the dust particles. This monitor for environmental protection, health, labor, Safety, military, education, family, etc for the particulate PM10 / monitoring of PM2.5. Features: 1. The real time measurement, direct reading PM2.5 and PM10 in ambient air, temperature and humidity parameter values, etc 2. Query at any time in the day and the average of a certain period of time 3. Can be divided into two kinds of online and on-site monitoring mode 4. The real time clock display, can display data curve for 24 hours, more intuitive understanding of the trend 5. Mass data storage, can save the monitoring data of 220 days 6. Can the mobile phone via bluetooth data transmission, the transmission distance of 10 m (optional) 7. Can send data to a phone via SMS way (optional) 8. Handheld compact design, beautiful shape, small volume, light weight, easy to carry 9. A touch of color display, illustrated, the operation is simple 10. The built-in efficient lithium battery, can be in normal use without external power adapter 11. With super threshold automatic buzzer alarm function 12. The battery real-time display, low battery tip charge function
