G10 Portable TDLAS Methane Gas Detector with Integrated Sampling Pump

G10 Portable Methane Detector for On-Site Gas Analysis

The G10 is a portable methane detection instrument developed for field inspections across natural gas infrastructure and industrial facilities. By combining laser absorption analysis with integrated gas sampling, it enables technicians to obtain methane concentration readings directly at inspection sites without relying on bulky, separate sampling equipment.

Integrated Sampling for Streamlined Inspections

The built-in gas pump draws samples into the instrument for analysis, while the integrated filtration system supports sample handling during field operations. This configuration simplifies equipment setup and helps technicians move efficiently between inspection points, including valves, pipe joints, connectors, and other potential leak locations.

Fast Measurement for Timely Decisions

During leak investigations, prompt access to concentration readings helps technicians evaluate suspicious areas and determine where additional checks may be necessary. The G10 provides rapid measurement feedback, supporting practical on-site assessments and reducing delays in the inspection workflow.

Continuous Reference for Measurement Stability

A built-in gas reference supports automatic self-calibration during operation, helping maintain consistent measurements over the course of fieldwork. This feature reduces dependence on frequent manual calibration adjustments, while routine maintenance and verification should still follow the manufacturer's guidance.

Laser-Based Methane Identification

The G10 uses Tunable Diode Laser Absorption Spectroscopy (TDLAS) to measure methane through its characteristic optical absorption. This selective measurement approach supports targeted methane analysis in natural gas inspection and industrial leak investigation, helping operators make informed decisions based on field readings.

Adaptable to Different Inspection Setups

Designed for mobile field use, the G10 can be deployed as a handheld instrument or integrated into suitable trolley-based and electric-bicycle inspection configurations. This flexibility allows inspection teams to adapt their equipment setup to different routes, site layouts, and operational requirements.

Typical Applications

• Natural Gas Networks: Inspect pipeline connections, valves, joints, and distribution infrastructure for potential methane leaks.

• Urban Gas Inspection: Support routine surveys of gas distribution assets and service connections.

• Industrial Facilities: Investigate suspected leaks around gas-handling systems, processing equipment, and storage installations.

• Landfill and Biogas Sites: Conduct methane screening where gas emissions require assessment.

• Field Leak Investigation: Obtain portable, on-site methane measurements to support preliminary assessment and follow-up inspections, subject to applicable safety procedures.

Practical Methane Analysis Wherever Inspections Take Place

With integrated sampling, laser-based measurement, and automatic self-calibration, the G10 brings essential gas analysis functions into a portable field instrument. Its adaptable deployment options and rapid measurement feedback help inspection teams carry out routine surveys and investigate suspected methane leaks more efficiently.
