Background：

Formaldehyde, with the chemical formula HCHO, is a colorless gas with a strong and pungent odor. It is gaseous at room temperature and volatile at room temperature. The World Health Organization has identified it as a carcinogenic and teratogenic substance. It is also a source of allergic reactions and one of the potential strong mutagens. Studies have shown that the release cycle of formaldehyde in decoration and furniture is as long as 3-15 years. Therefore, it is necessary to detect the formaldehyde concentration. Formaldehyde sensor is a component that people use to detect formaldehyde gas. There are many kinds of formaldehyde detection instruments on the market. Most of them use electrochemical methods to detect formaldehyde.

Features:

The formaldehyde gas detector uses a highly sensitive electrochemical principle,combined with microcontroller technology and network communication technology. We collect air samples at the test site, and the sensors will obtain different potential signals due to different formaldehyde concentrations.  And further show the formaldehyde concentration. Through the detection of formaldehyde gas in the air, we can analyze the formaldehyde concentration and carry out high-precision tests.

Compared with other methods, the formaldehyde sensor has the advantages of strong anti-interference ability, high sensitivity, accurate measurement results, and good recovery response characteristics. Therefore, most people recognize the detection principle of formaldehyde, which is the focus of future research on formaldehyde gas sensors.

The CH2O gas sensor have strong anti-interference ability, high sensitivity, high resolution, small volume, easy installation, no need for secondary calibration, support secondary development.The sensor and small volume, light weight, easy installation and other characteristics, can be used for portable, fixed, pipeline and other appearance sensors.  The CH2O gas sensor module is widely used in the production and installation of portable and fixed gas detectors. And various gas detection occasions and equipment.
