Brand introduction of formaldehyde detector
First, think about music and wisdom.
Silezhi is an international first-line brand, specializing in the production of household measuring instruments. Its products are rich and varied, especially the research and development of formaldehyde detector. Silezhi formaldehyde detector uses the working principle of high-sensitivity electrochemical sensor to absorb formaldehyde in the air and then react with colored compounds. Users can know whether the indoor formaldehyde content exceeds the standard according to the color comparison.
Silezhi formaldehyde detector is simple in structure, small and exquisite, and can quantitatively and qualitatively determine formaldehyde components in indoor air. Because of its small size, it is easy to carry and use indoors or outdoors, even in public places.
Second, Haier
Many people know that Haier is a large household appliance enterprise, but Haier's products are not only that, but also the formaldehyde detector produced by Haier is well received by consumers. Because Haier's formaldehyde detector is easy to use and has an LCD screen, it can directly help people understand the formaldehyde content in the surrounding air, so it is favored by consumers.
Moreover, the biggest feature of Haier formaldehyde detector is that its accuracy is much higher than many other brands. This is an intelligent instrument. It is made of high-resolution and high-precision chips. Even better, Haier formaldehyde detector can be controlled remotely. It can monitor the ambient air quality in real time, and the price is not expensive, which is suitable for ordinary consumers.
Third, Miao Chuang
Formaldehyde detector is one of the products promoted by Miaochuang. It has an air radar inside, and users can monitor the formaldehyde content in indoor air for 24 hours. Not only that, Miaochuang formaldehyde detector can also detect the content of other gas components in the air, air humidity, air pollution index and so on. Its noble design is suitable for all kinds of occasions.
The formaldehyde detector developed by Miaochuang has two modes, namely standard mode and sleep mode. Among them, the sleep mode is usually used at night. When the sleep mode is turned on, there will be no sound interference and discomfort caused by light intensity, and the design of Miaochuang is more humanized. It uses mixed alloy to make the shell, which achieves the effect of anti-fall and compression, and is deeply loved by consumers.
Fourth, safety.
Jia Baoyu's formaldehyde monitor is a household formaldehyde monitor produced by Gu Bei Science and Technology Co., Ltd. The product adopts the latest imported electrochemical sensor and high-precision operational amplifier chip, which can directly convert the formaldehyde concentration signal in the air into an electrical signal in real time and continuously, and display the measurement results in LCD digital mode after data processing by microcomputer. Jia Baoyu broke the technical bottleneck that the traditional formaldehyde detector is bulky, expensive and can only detect once, and provided 24-hour uninterrupted real-time monitoring of indoor formaldehyde concentration. Jia Baoyu's 24-hour household formaldehyde monitor is beautiful and elegant in design, simple and convenient to operate, and fully protects the health and safety of you and your family.

Seven, acetaldehyde know?
Haier Aldehyde knows that it is an intelligent monitoring and analysis platform for formaldehyde produced by Haier's technology research and development team, which can systematically display the measurement results and remind users of the countermeasures under various pollution conditions.
Working principle:
The formaldehyde detector adopts the principle of high-sensitivity electrochemical sensor, combined with single chip microcomputer technology and network communication technology to collect and detect air samples at the scene. Formaldehyde in the air is absorbed by phenol reagent solution to generate azine, which is oxidized by trivalent iron ions in acidic solution to generate blue-green compounds. According to the color depth, direct colorimetric determination is carried out on the spot.
Because the detection value of indoor pollution has a great relationship with the temperature, humidity and air pressure of the detection environment, according to normal detection, the detection value often deviates from the expected value.
The machine in the picture on the right is a five-in-one detector, which can quickly detect indoor pollutants such as formaldehyde, benzene, ammonia, toluene, xylene and TVOC, display the date and detection time, and detect temperature and humidity data on the spot. On the left is a Chinese LCD screen, on the right is sampling timing operation, and in the middle is a thermal printer, which can quickly sample and analyze in real time on site, and can print the date and time, temperature, humidity, implementation standard, formaldehyde content and whether it is qualified or not into a report. Formaldehyde detection adopts national standard phenol reagent spectrophotometry and imported photoelectric sensor, which has high detection accuracy and low detection limit, and solves the shortcomings that the sensor zero of electrochemical formaldehyde detector is easy to drift and is easily disturbed by other chemical gases when sampling.
In addition to formaldehyde law:
Ventilation method
Ventilation method does not need too much explanation, that is, it discharges harmful gases to the outside through the flow of air. This is a simple and effective method. The only drawback is that the formaldehyde release cycle is long, usually three to fifteen years. It is obviously unrealistic to leave the new house idle for more than three years after renovation. Because of this, ventilation alone cannot meet the requirements.
physical method
Activated carbon, coconut charcoal and other materials are mainly used to adsorb polluted gases, which is not only physical adsorption, but also the best physical removal method at present. The principle is that the porous structure of activated carbon provides a large amount of surface area, which makes it very easy to absorb and collect impurities. Just like magnetic force, all molecules attract each other. Because of this, a large number of molecules on activated carbon can produce strong attraction, so as to attract impurities in the medium to the pore size.
Chemical method
Its principle is that chemical substances and harmful gases change chemically, such as nanotechnology, photocatalyst, formaldehyde remover, deodorant and so on. Oxidizing polluted gas. In addition, various electric air purifiers can also play the role of physical and chemical treatment.
biological method
Mainly use plants to absorb indoor air pollution, purify indoor air, or use microorganisms and enzymes for biological oxidation decomposition.
The above are the brands of formaldehyde detector recommended by Bian Xiao, hoping to help readers.
