Diffusion VOC Detector

The diffusion-type VOC detector allows gas to naturally diffuse into the sensor, utilizing semiconductor or electrochemical principles to detect the concentration of volatile organic compounds. It is used for rapid on-site monitoring of VOC levels in the air and is suitable for gas leak detection in enclosed environments such as printing workshops and paint production lines.
Selection
When selecting, consider that the detection range must cover the target gas concentration, the response time meets monitoring requirements, the sensor lifespan and maintenance costs align with usage frequency, the protection rating suits the on-site environment, and the data recording function complies with regulatory requirements.
