ETO Gas Detector Fixed Ethylene Oxide Sterilization Safety Monitoring System Industrial Toxic Gas Alarm Gas Sensor
Our company's online gas detector utilizes original imported smart gas sensors, serving as an intelligent, high-performance instrument capable of continuous online monitoring of combustible gases, toxic/hazardous gases, and specialty gases.
Featuring an integrated flameproof enclosure structure, the detector delivers high sensitivity and precision. Through connection to a GDS gas alarm controller and monitoring management software, it enables real-time concentration display on computers. Additionally, by incorporating an optional wireless module, real-time monitoring data and alarm status can be transmitted to safety control centers.
