G10 Portable TDLAS Methane Detector with Internal Pump for Pipeline Inspection

Product Specification

G10 Portable Laser Methane Detector for Efficient Leak Inspection

The G10 is a portable TDLAS laser methane detector designed for natural gas pipeline inspection and industrial leak detection. Combining an integrated gas sampling pump with laser-based measurement technology, it helps operators identify potential methane leaks and assess gas concentrations directly in the field.

Designed for efficient inspection workflows, the G10 supports routine maintenance, targeted leak investigations, and gas monitoring across different working environments. Its portable configuration gives technicians the flexibility to inspect individual components or cover broader areas using suitable mounting and sampling arrangements.

Integrated Pump for Efficient Gas Sampling

The G10 features a built-in gas sampling pump that draws gas into the detection system for analysis. Combined with an efficient filtration system, it supports a streamlined sampling process for field inspection tasks.

The integrated design reduces the need for separate pumping equipment and helps technicians move between inspection locations more conveniently. It is suitable for examining accessible pipe connections, valves, joints, and other potential leak points across natural gas infrastructure.

Rapid Response and Real-Time Gas Monitoring

The G10 provides real-time methane measurements to help operators assess changing gas concentrations during inspections. Fast measurement feedback allows technicians to review potential leak indications promptly and determine whether further investigation is necessary.

By bringing gas analysis directly to the inspection site, the system helps streamline field operations, supports timely decision-making, and reduces delays in evaluating suspected leak locations.

Automatic Self-Calibration for Consistent Measurements

The G10 incorporates a built-in gas reference that supports continuous self-calibration during operation. This function helps maintain measurement consistency and reduces the need for frequent manual calibration interventions during routine use.

The reference system works alongside the laser detection technology to support repeatable field measurements. Regular maintenance and calibration checks should still follow the manufacturer's recommendations.

TDLAS Technology for Selective Methane Detection

Using Tunable Diode Laser Absorption Spectroscopy (TDLAS), the G10 detects methane through its characteristic optical absorption properties. The system analyzes laser absorption signals to determine methane concentration in the sampled gas.

This selective laser-based approach is suitable for natural gas leak investigations and industrial monitoring, where operators need targeted methane measurements to support inspection and maintenance decisions.

Flexible Installation and Field Operation

The G10 is designed for portable use and can be configured for suitable trolley-based or electric-bicycle-mounted inspection workflows. These options allow operators to adapt equipment deployment to site conditions and survey requirements.

Whether used for targeted inspections or routine surveys across accessible pipeline routes, the G10 offers a flexible approach to field gas detection and measurement.

Applications

Natural Gas Pipeline Inspection

Inspect accessible pipelines, valves, joints, connections, and related infrastructure for potential methane leaks.

Urban Gas Utility Surveys

Support routine inspection of gas distribution networks and service connections to help identify locations requiring further assessment.

Industrial Facility Monitoring

Conduct leak investigations around gas-handling equipment, refineries, chemical plants, and other industrial installations.

Landfill and Biogas Monitoring

Assist with methane screening at landfills and biogas facilities where gas emissions may require monitoring.

Emergency Leak Investigation

Provide portable, on-site methane measurements during preliminary assessments of suspected gas leaks, following applicable safety procedures.

A Practical Solution for Everyday Methane Inspection

The G10 combines integrated gas sampling, laser-based methane detection, and automatic self-calibration in one portable instrument. Its real-time measurement capability and flexible deployment options help inspection teams organize fieldwork, assess potential leaks, and support follow-up maintenance across natural gas and industrial infrastructure.
