Portable TDLAS Methane & Ethane Detector for Natural Gas Leak Inspection
Product Introduction
The portable TDLAS methane and ethane detector is designed for fast and accurate gas leak inspection in natural gas pipelines, storage facilities, and industrial environments. Using Tunable Diode Laser Absorption Spectroscopy (TDLAS), the detector measures methane (CH₄) and ethane (C₂H₆) and provides direct concentration information for field inspection.
Methane and Ethane Measurement
By detecting both methane and ethane, the system provides additional gas composition information for natural gas leak identification. Operators can compare the measured methane and ethane concentrations and their proportions to help assess whether a detected gas source is associated with natural gas.
PPB-Level Laser Detection
Laser-based detection technology provides high sensitivity and supports ppb-level measurement, allowing the system to identify low-concentration gas signals. Fast laser measurement also provides timely concentration information during inspection.
Portable Field Inspection
The compact portable design is suitable for mobile gas surveys and inspection tasks where operators need to move between different measurement points. Laser-based remote sensing can also help users detect gas leaks from a safer distance where direct access may be difficult.
Broad Monitoring Applications
The detector can be used for natural gas pipeline leak detection, storage facility inspection, industrial gas monitoring, and environmental emission monitoring. The supplied product information also identifies potential applications in breath gas analysis.
