Formaldehyde is a colorless gas with a strong odor and is one of the primary sources of indoor air pollution. It poses significant risks to human health, potentially causing respiratory diseases and skin allergies. Therefore, detecting formaldehyde concentration in indoor air is of paramount importance.

An electrochemical formaldehyde sensor operates based on electrochemical reaction principles. It offers advantages such as high sensitivity, fast response, good stability, and strong anti-interference capability, making it widely used in indoor air quality detection.

The advantages of electrochemical formaldehyde sensors in indoor air quality monitoring are reflected in several aspects:

● High Sensitivity: These sensors can detect low concentrations of formaldehyde. According to relevant standards, the maximum allowable concentration of formaldehyde in indoor air is 0.1 mg per cubic meter. Electrochemical formaldehyde sensors can accurately detect this concentration, providing reliable data for indoor air quality assessment.

● Fast Response: The response speed is rapid, enabling the detection of changes in formaldehyde levels in real time, which is critical for monitoring.

● Good Stability: Performance does not change significantly during long-term use, ensuring the ongoing accuracy of detection results.

● Strong Anti-interference: They can resist the influence of other gases in the air, which is essential for accurate testing in complex environments.

In summary, electrochemical formaldehyde sensors have clear advantages and are currently one of the most widely used types of formaldehyde sensors for indoor air quality detection.
