View - TVOC sensor
Environmental pollution caused by interior decoration has attracted more and more attention, and TVOC is the most serious of the three organic pollutants (polycyclic aromatic hydrocarbons, volatile organic compounds, and aldehydes) in the air. VOC refers to organic substances whose saturated vapor pressure exceeds 133.32pa at room temperature, its boiling point is between 50°C and 250°C, and exists in the air in the form of evaporation at room temperature. Its toxicity, irritation and carcinogenicity can affect the skin and mucous membranes, cause great damage to the human body. The TVOC sensor launched by our company can effectively monitor the TVOC content in the environment.
Description of TVOC sensor
The TVOC sensor collects data and uploads the data to the cloud platform through the concentrator. The cloud platform supports computer terminal and mobile terminal login. Users can log in anytime and anywhere through the account password to view the real-time and historical data of indoor TVOC gas concentration.
Through the cloud platform, we can set the upper limit alarm value of indoor TVOC gas concentration. For example, the alarm value is set to 0.28mg/m³. If the TVOC gas concentration approaches or reaches the limit value, the cloud platform will send a platform alarm, SMS alarm, email alarm, etc. Notify the manager as soon as possible and take timely measures to reduce the TVOC gas concentration.

FAQs
Usually, we call formaldehyde, benzene, ammonia, xylene and other volatile gases in the indoor environment TVOC gas.
0.5 mg/m3
“According to the specified standard, the safe value of one cubic meter of TVOC should be within 0.5mg/m3. If the measured TVOC value exceeds this standard, it means that the pollution in the air is relatively serious.
TVOC can cause serious indoor air pollution and cause imbalance of human immune level. Affect the function of the central nervous system, causing headache, weakness, chest tightness and other symptoms. It may also affect the digestive system, resulting in loss of appetite and nausea. In severe cases, the liver and hematopoietic system can be damaged.
An TVOC sensor is used to detect Total Volatile Organic Compounds in your environment. It does this by identifying vapours of gases given off by volatile compounds.
The sum of all VOCs is called total volatile organic compounds (TVOC). The gas volume of each category and the sum of all gases (TVOC) is an important reflection of the relevant organic compounds found in indoor air.
The working principle of the Tvoc sensor is relatively simple. When the detected gas exists in the air, the conductivity of the sensor changes. The higher the concentration of the gas, the higher the conductivity of the sensor.
According to the different installation methods in different places, it can be roughly divided into three types: wall-mounted TVOC meter, explosion-proof TVOC gas detector, and portable TVOC gas detector
TVOC gas detector is suitable for oil extraction, smelting, chemical industry, municipal administration, sewage treatment, power gas, mining, tunnel construction, fire storage, papermaking, pharmaceutical, brewing and other environments that need to detect toxic and harmful gases for work!
The calibration of tvoc meter is technical work, please contact professional technicians.
