Test for formaldehyde for health
What is formaldehyde? What are the hazards of formaldehyde? Have you known all of this? Why do we need toxic and harmful gas sensor to detect it?
What is formaldehyde
Formaldehyde is also called formic aldehyde. It is a colorless gas. It has a strong irritating odor and has a stimulating effect on human eyes and nose. The main hazard of formaldehyde is the strong irritant effect on the skin and mucous membranes. When formaldehyde reaches a certain concentration indoors, people feel uncomfortable. The formaldehyde concentration greater than 0.08m³ can cause red eyes, itchy eyes, throat discomfort or pain, hoarse voice, sneezing, chest tightness, asthma, dermatitis and other symptoms. The newly renovated room contains high formaldehyde content, which is the main cause of many diseases.
The harm of formaldehyde to the human body
Long-term, low-concentration exposure to formaldehyde can cause headaches, dizziness, fatigue, sensory disturbances, and reduced immunity. There may be drowsiness, memory loss or neurasthenia, and depression. Chronic poisoning is also harmful to the respiratory system. Long-term exposure to formaldehyde can cause respiratory dysfunction and liver toxic lesions. Manifested as liver cell damage, abnormal liver radiation energy, etc. The most serious thing is that formaldehyde vapor forms an explosive mixture with air, which can cause combustion and explosion when exposed to open flames and high heat energy. In case of high heat, the internal pressure of the container will increase and there is a danger of cracking and explosion. This impact is extremely large. In summary, the toxic and harmful gas sensor is very important and indispensable for the gas monitoring of formaldehyde.
The fixed formaldehyde gas alarm independently developed by Jingxunchangtong uses a professional test formaldehyde concentration sensor probe as the core detection device. It has the characteristics of wide measuring range, high precision, good linearity, good versatility, convenient use, easy installation, long transmission distance, and moderate price. The explosion-proof formaldehyde sensor can monitor the concentration of formaldehyde gas in the environment or in the pipeline and alarm. Make gas monitoring more accurate and reliable, with temperature compensation, which can perfectly realize the compensation of gas concentration in different temperature environments. With two-level sound and light alarm, the response speed is fast, and the reminder is more obvious.
