SF6 and Oxygen Gas Detector

SF6 and Oxygen Gas Detector

SF6 and oxygen gas detector is used for real-time monitoring concentration of sulfur hexafluoride and oxygen as well as ambient temperature and humidity in the workplace of indoor electrical equipment so as to give early warning according to the alarm limit settings which is widely used in gas analysis industry, industrial process control, environmental detection and power plant substations and other fields. The detector is also equipped with a PIR (Passive Infrared) sensor to sense human body for safety reason. Detection data can be uploaded in real-time through RS485 or Wi-Fi to a controller or cloud.
