Portable G10 TDLAS Methane Detector with Trolley for Gas Leak Inspection

G10 Portable TDLAS Laser Methane Detector

The G10 is a portable laser gas detection system designed for natural gas leak inspections and industrial gas monitoring. Combining TDLAS sensing technology with flexible sampling options, it helps operators investigate suspected leaks across pipelines, facilities, and other gas-related infrastructure.

Its adaptable configuration supports operation with a trolley or sampling probe, allowing inspection teams to select a suitable working method for different site conditions. The fast-disassembly design also simplifies equipment handling, transportation, and preparation between inspection tasks.

Flexible Sampling for Different Inspection Environments

The G10 supports trolley-based and probe-based sampling to accommodate different inspection workflows. The trolley configuration is suitable for systematic surveys across accessible areas, while a probe can help operators examine specific locations where more targeted sampling is needed.

A high-flow gas sampling pump and integrated filtration system help maintain a practical sampling workflow in field environments. The system can also be configured for mounting on a trolley or compatible electric bicycle, supporting mobile inspection across larger sites.

Continuous Self-Calibration for Reliable Measurements

The G10 incorporates a built-in gas reference that supports ongoing self-calibration during operation. This function helps maintain measurement consistency and reduce the need for frequent manual calibration interventions, subject to the instrument's operating and maintenance requirements.

Its laser-based detection technology is designed for selective methane measurement, supporting the identification of suspected gas leaks in environments where reliable gas readings are important for inspection decisions.

Real-Time Analysis and Flexible Concentration Readings

The G10 provides real-time gas measurements to help operators assess changing methane levels during field investigations. Its display supports concentration readings in multiple formats, including ppm, %LEL, and %VOL, making it easier to interpret results for different inspection and reporting requirements.

By presenting measurement information directly at the inspection site, the system helps teams assess potential leak indications and determine whether additional investigation is necessary.

TDLAS Technology for Methane Detection

The G10 uses Tunable Diode Laser Absorption Spectroscopy (TDLAS) to detect methane through its characteristic light absorption properties. This optical measurement approach supports selective gas detection and is suitable for leak inspection across natural gas infrastructure and industrial environments.

Combined with adaptable sampling equipment, the G10 provides a practical option for both targeted leak investigation and routine inspection work.
