The days of difficulty in breathing continue due to COVID-19, but the yellow dust from the Gobi Desert recently made it harder to breathe for several days. Fortunately, it’s raining today, so I’m going to see a day without fine dust for the first time in a while. It’s been a long time since Korea wore a mask with fine dust, but I feel really sorry for the children because they think they will probably live with it for the rest of their lives. When I was very sensitive to fine dust, I bought an interesting one. Until a few years ago, some people made their own fine dust measuring instruments and installed them at home, but I didn’t have that ability, so I bought portable ultrafine measuring instruments. Today, I’d like to introduce the fine dust measuring instrument that I have.

CALDER PM2.5 MEASURING INSTRUMENT
This product is designed to measure yellow dust, fine dust, fine dust, formaldehyde, and even volatile organic compounds.
Because it is portable, the shape is easy to hold with one hand. They say it’s rechargeable to carry a cell phone. Of course, this product is rechargeable. As if charging a smartphone, it is charged with a micro 5-pin terminal and has a built-in 1200mAh lithium-ion battery.
You can use it standing up with the stand spread out at the back.
The air inlet for measuring dust is located on the top and left and right sides.
You can see a little bit of the measurement sensor on the right side of where the air enters.
If you look at the calder measuring instrument, it tells you three types of air quality Formaldehyde 0.026 μg/㎥, particulate matter 16 μg/㎥, and volatile organic compound (TVOC) were measured at 0.225 μg/㎥ from the top.On the right side, the air purifier shows fine dust at 13-14 μg/㎥, but there seems to be no significant deviation from the calder measuring instrument.
The round device on the right is a device that measures carbon dioxide, fine dust, and fine dust. Similarly, there is no difference between the calder meter and the PM2.5. Currently, fine dust is 14μg/㎥. Because of this level of accuracy, sometimes fine dust is measured in the car and fine dust in the office, but these days, passenger cars have air purification filters in the car, so fine dust and fine dust are less than expected.There were few offices, but the number of volatile organic compounds is a little high, perhaps because there are many personal computers, but I don’t really care. However, if you live safely in an office where there are no windows and you can’t ventilate, you can see that Kindabus is growing throughout the office.If you press the Fn button on the left, fine dust (fine dust below 1 μm), fine dust (fine dust below 2.5 μm), and fine dust (fine dust below 10 μm) will be displayed on the LED screen.It usually shows the numerical values of formaldehyde, particulate matter, and volatile organic compounds.On the left is the measurement of formaldehyde, fine dust, and organic compounds, and on the right is the measurement of fine dust, fine dust, and fine dust. CALDER FINE DUST MEASURING INSTRUMENT-FORMALDEHYDE AND VOLATILE ORGANIC COMPOUND MEASURING METHODAlthough fine dust is measured as soon as it is powered on, formaldehyde and volatile organic compounds have several procedures before measurement.When the first Karda PM2.5 measuring instrument is turned on, it will be on the counter from 180 seconds to 0 seconds. If you do it in a place with clear air, you can set it up accurately.Then, stay still for 8 minutes. I adjusted it to 8 minutes with a timer^^After 8 minutes, press the adjustment button in the middle for 3 seconds to align with 0. If I put it on top of the air purifier, all the numbers are zero. And after 5 minutes, the measured value will come out.I put the measuring instrument on the table I use. Five minutes later, the measurement was 0.015 μg/㎥ of formaldehyde and 0.15 μg/㎥ of organic compounds. It’s a bit troublesome, but I think you can write it like this. You can buy new furniture or use it in a new apartment. You don’t seem to use it very often. Since fine dust measurements can be made immediately, the frequency of use will be used a lot for fine dust measurements. Since we are a family with rhinitis, there are many kinds.I put the measuring instrument on the table I use.
