VOC Composite Gas Detector

VOC composite gas detectors adsorb volatile organic compounds through sensors, which cause changes in electrical signals that are converted into concentration readings. They are used for on-site monitoring of leaks of mixed gases such as benzene and ketones in processes like printing and coating, ensuring the safety of the working environment.
Selection
When selecting, confirm that the detection gas type and range match the on-site requirements, paying attention to the sensor's anti-interference capability and response speed. It is necessary to consider the explosion-proof rating, data recording function, and calibration cycle to meet the long-term stability requirements under different working conditions.
