Harmful Gas Detection Sensor

Harmful gas detection sensors generate changes in electrical signals through the electrochemical or semiconductor components reacting with target gases, and are used to monitor the concentration of specific gases in the environment. They are commonly employed in the fields of industrial safety monitoring and environmental protection testing.
Selection
When selecting, it is essential to clearly identify the types of gases to be measured, consider the detection range, response time, service life, and explosion-proof rating, and take into account factors such as temperature, humidity, and interfering gases in the usage environment to ensure the sensor matches the detection requirements.
