Product Overview
The Infrared Combustible Gas Detector (Methane Detector) utilizes advanced NDIR (Non-Dispersive Infrared) gas analysis technology, designed specifically for detecting and alarming methane (CH₄) gas leaks in natural gas, coalbed methane, landfill sites, wastewater treatment, and anaerobic fermentation environments. The device accurately detects methane gas concentrations and triggers alarms when leakage exceeds preset thresholds, ensuring a safe working environment. Its infrared gas filtering technology ensures that methane measurements are not affected by other gases, delivering high-precision detection results.
Key Features
- Infrared Gas Filtering Technology: Employs infrared gas filtering technology to ensure methane measurements are free from interference from other gases, providing precise detection data.
- Oxygen-Free Environment Capability: Operates effectively in oxygen-deficient environments, suitable for a range of specialized applications.
- Temperature Compensation and Automatic Calibration: Includes temperature compensation and automatic zero-point calibration functions, ensuring stability and accuracy under various environmental conditions.
- Long-Life Sensor: Equipped with a long-life sensor that is resistant to sensor poisoning, extending its service life and reducing maintenance needs.
- Explosion-Proof Design: Explosion-proof rating of Ex d II C T6 Gb, ensuring compliance with safety standards for gas leak detection in high-risk environments.
Applications
- Natural Gas and Coalbed Methane Monitoring: Used in the production, transportation, and storage of natural gas and coalbed methane to monitor methane gas leakage.
- Landfill Sites: Monitors methane gas leakage in landfill sites, preventing potential explosion risks.
- Wastewater Treatment Facilities: Monitors the leakage of methane and other combustible gases in wastewater treatment processes, ensuring worker safety.
- Anaerobic Fermentation Processes: Suitable for detecting gas leaks in anaerobic fermentation and other gas-generating environments.
