Usage:

Press and hold the power button for 3 seconds to boot, remove the sampling port on the dust cover, install the sensor of temperature and humidity (insert aligned with gap), press run / stop button to start the test, each test process takes 60 seconds to ensure that the sample is representative, as close as possible the average value the surrounding air, after finished testing automatically display the results,

If you need to do more tests, then press run / stop button again, if need to stop midway, press the run / stop button to stop.

After testing, record data, and then press the power button off, put dust cover

It is portable, keep records pm2.5 situation around the air, in order to determine the suitability to go out exercising or other outdoor activities.

 

Remarks:

Who requirements: pm2.5 less than 10 micrograms / cubic meter is a safe value, European standard: pm2.5 not more than 35 micrograms / cubic meter, the air quality is good. National Standard: pm2.5 annual average of less than 70 micrograms / cubic meter of air quality as good.

When pm2.5 more than 70 micrograms / cubic meter, it is recommended to minimize outdoor exercise.
