| High Light | Fixed Multi Gas Leak Detector ，Explosion Proof Multi Gas Leak Detector | ||
Equipped with original imported intelligent gas sensors, this is a high-performance intelligent detection instrument capable of continuous online monitoring of multiple gases. The detector features an integral explosion-proof structure with high sensitivity and precision. Real-time gas concentration data can be displayed on a computer through a gas alarm controller and monitoring software. Additionally, optional wireless modules enable real-time transmission of monitoring data and alarm statuses to safety control centers. It is widely applicable across industries such as petroleum/petrochemicals, metallurgy, environmental protection, gas, fire safety, municipal services, chemical engineering, shipbuilding, power generation, process control, wastewater treatment, and emergency rescue monitoring.
