In recent years, haze has become more and more serious, and the harm of PM2.5 has attracted more and more attention.

PM2.5 can enter the blood through bronchi and alveoli, and harmful gases, heavy metals, etc. are dissolved in the blood.

The World Health Organization pointed out in the 2005 edition of the Air Quality Guidelines that when the annual average concentration of PM2.5 reached 35 micrograms per cubic meter, the risk of human death was about 15% higher than that of 10 micrograms per cubic meter.

Therefore, the air purifier products have naturally become necessities of our lives. Even my car has been replaced with PM2.5 proof air conditioning filter elements at home, which makes me feel comfortable and safe to breathe.

So how to quickly, real-time and accurately judge the PM2.5 concentration of indoor and outdoor air quality detection? How to detect the real effect of the PM2.5 air conditioning filter element in our home~car?

The effect of anti PM2.5 air conditioning filter element can only be measured by ourselves.

The air quality sensor of the air purifier is limited by the product cost, and the sensor of the air purifier is generally insufficient in data accuracy and real-time.

In addition, the sensor attached to the purifier may not accurately reflect the indoor remote air quality due to the interference of the purifier airflow after the purifier runs for a period of time. In real life, we cannot always sit beside the purifier.

Therefore, an accurate and reliable portable detector can help us understand the air outlet data of the air purifier and the air quality data of the far end of the room, so that we can accurately judge whether the purifier we are currently using meets the purification needs of the room area to protect our respiratory health.

This requires an accurate and reliable PM2.5 detector to help us. The 352 PM2.5 air detector uses the highest accuracy laser sensor for civil use at present.

And each set has been calibrated by the expensive industrial TSI8530 atmospheric environment particle detector.

The 352 PM2.5 detector adopts an integrated aluminum alloy body shell design, with 352 logo and a multi-color status indicator light on the front.

It is green when working and orange when charging.

A charging cable is included with the accessory.

The measuring air inlet, outlet, switch and charging port of 352 PM2.5 detector are set on the back

The top screen glass of 352 PM2.5 detector adopts 2.5D gorilla glass, with round corners and comfortable hand feel

The 352 PM2.5 detector adopts the laser sensor with the highest accuracy for civil use at present, and each of them has been calibrated by the expensive industrial TSI8530 atmospheric environment particle detector, with sensitive response and accurate measurement values.

Use a professional portable particle detector to compare the values accurately.

Next, let's test the effect of the indoor air purifier. The air purifier used is 352X80.

The PM2.5 data in the front room, the air outlet of the purifier and the door at the far end of the room are opened by the purifier.

Measure the data 15 minutes after the 352X80 air purifier is opened~the air outlet of the purifier~and the door at the far end of the room

It can be seen that the PM2.5 value at the far end of the room is below 10, indicating that the purifier performs well, and it is fully applicable to the current room area, which can ensure the indoor remote purification effect

The accurate and sensitive response speed of the 352 PM2.5 detector can be clearly seen from the following dynamic diagram.

The 352 PM2.5 detector can fully meet our measurement requirements for real-time accurate changes of PM2.5.

I believe that many friends who drive cars, like me, have chosen to replace the air conditioning filter element with the PM2.5 filtering function to deal with the PM2.5 in the car.

The advantage of the PM2.5 filter element is that it is economical, and unlike the on-board purifier, it needs power supply and wiring, which takes up space in the vehicle and may cause potential safety hazards~

So how to know conveniently, quickly and accurately whether the PM2.5 filter element we replaced has a good PM2.5 filtering effect?

Just take the 352 PM2.5 detector.

PM2.5 value inside the vehicle without closing the window:

PM2.5 value in the vehicle interior and air outlet after closing the window and opening the air conditioner for air change:

Obviously, the PM2.5 air conditioning filter element has a significantly good effect and can be relieved.

The 352 PM2.5 detector can not only provide us with portable and accurate real-time measurement, but also carry out remote monitoring measurement, data statistics and sharing through 325APP.

If 325 purifier equipped with WIFI linkage function is used, linkage control can also be carried out, which is very convenient.

Summary:
