Product Applications
1. Sensitivity can detect low concentrations: This sensor has "good eyesight" and is particularly sensitive to formaldehyde. Even if the formaldehyde concentration in the air is very low, it can accurately measure it and will not miss the inspection.
2. Real-time updates without delay: It can "watch" the change of formaldehyde concentration and tell you the latest data at any time, just like a live broadcast, so that you can immediately know whether the formaldehyde in the environment is over the limit or not.
3. Accurate measurement and small error: Some models use imported core detection parts, such as "high-precision ruler," and the measured formaldehyde value is very accurate, with almost no error, so don't worry about data deception.
4. It can remember data and "deliver messages": It comes with a "small ledger" that can record long-term changes in formaldehyde concentration; It can also "tell" the computer or mobile phone through wireless signals, which is convenient for you to analyze the change law of formaldehyde.
5. Energy-saving, durable, and cost-effective: In terms of design, it is very "electricity-saving". It can be used for a long time after charging once or replacing the battery. It does not need to be charged frequently, and it is not easy to break down. It can help you save money in the long run.
6. Strong anti-interference ability: If there are other interfering gases in the environment (such as smoke and odors), it can "stay stable" and not be affected, always focusing on measuring formaldehyde to ensure reliable data.

Common knowledge of CH2O
What is formaldehyde
Formaldehyde is a colorless, irritating-smelling gas with the chemical formula HCHO. It is often used in the manufacture of furniture, plywood, glue, paint, etc. It is a common indoor air pollutant. Long-term exposure to high concentrations of formaldehyde may irritate the respiratory tract and skin, and even affect health.
What are the harms of formaldehyde to the human body
Low concentration of formaldehyde may cause eye irritation, nasal congestion, cough and other discomfort; High-concentration contact may cause breathing difficulties and allergic dermatitis, and long-term exposure may increase the risk of nasopharyngeal cancer, leukemia, etc., especially harming sensitive groups such as children and pregnant women.
How to reduce indoor formaldehyde pollution
Formaldehyde pollution can be reduced in the following ways:
· Ventilation: Keep windows open for a long time after decoration to accelerate the evaporation of formaldehyde.
· Choose eco-friendly materials: When purchasing furniture and decoration materials, look for eco-friendly standards with low formaldehyde release (such as E0 grade).
· Use purification equipment: install air purifiers (with activated carbon or photocatalytic function) and place adsorbent plants such as maidenhair ferns to assist purification.
· Professional treatment: Please have a professional organization test and treat indoor air (such as formaldehyde remover, sealing agent, etc.).
Application Scenarios
Industrial production
Waste gas emission monitoring: Conduct real-time monitoring of industrial waste gas emissions to ensure that waste gases meet emission standards and reduce pollution to the environment.
Environmental inspection
Air quality monitoring helps people understand air quality and protect the environment and health by detecting harmful gases such as sulfur dioxide.
Safety protection
In coal mines and tunnels, gas sensors detect toxic and harmful gases such as methane and warn against accidents.
