Fixed On-line Oxygen Detector

Online oxygen detector uses intelligent original imported sensors, which is an intelligent high-performance detection instrument that can continuously monitor oxygen gas and has a real-time alarm function. The overall flameproof structure of the instrument has stable signals, high sensitivity and precision. The detector can realize the real-time concentration display on the computer through the gas alarm controller and monitoring management software. It can also transmit the real-time detection data and alarm status to the security control center through the optional wireless module. They can be widely used in metallurgy, petroleum and petrochemical, municipal, chemical, marine, process control and other industries.


◆ Imported high-performance electrochemical oxygen sensor with a service life of more than 2-3 years;
