When to use Laser Gas Detection

Laser Gas Detection provide a solution to various gas detection challenges within emission monitoring and process control. Laser gas detectors use a near identical infrared technology to that seen on our other products, but where the transmitter and receiver are separated by a distance. When methane passes between the two, the ‘beam is broken’ and the receiver will let you know the concentration of gas.  

Leak detection of common gases usually detects flammable or explosive gas. This means that traditional (i.e., catalytic) leak detection methods are inadequate to successfully detect at a distance. This means that all gas resources or transmission lines must be observed in terms of a gas leakage.  

Using a Laser Gas Detector 

Laser technology enables gas leaks to be located, by pointing the laser beam towards the suspected leak, or along a survey line. Being very intuitive and easy to use, it is practically ‘point and shoot’ with a 2-button operation and touch display. The laser beam pointed towards areas such as gas piping, the ground, joins etc, is reflected from the target. The device receives the reflected beam and measures the absorptivity of the beam, which is then calculated into methane column density (ppm-m) and displayed clearly on the display. 

Laser gas detectors allow for the detection of methane gas from a safe distance without the need for a worker to enter certain hazardous areas. Utilising infrared laser technology, methane leaks can be efficiently confirmed through the use of pointing a laser beam towards the suspected leak, or along the survey line. This revolutionary technology removes the need to access elevated places, under floor, hazardous areas or other hard to reach environments. It is also ideal for surveying large open spaces e.g., landfills or studying agricultural emissions. 

L-Tek P100

Laser-based gas sensing technology provides a fast, effective, and reliable method for detecting methane emissions. By using advanced laser technology, the L-Tek P100 can quickly identify methane leaks from a safe distance, helping operators locate emission sources efficiently while reducing exposure to potentially hazardous environments.

The L-Tek P100 is a lightweight, handheld remote methane detector designed for rapid leak detection and survey applications. Capable of detecting methane concentrations from distances of up to 100 metres, the device enables users to inspect pipelines, gas infrastructure, and difficult-to-access areas without the need for direct contact with the source of the leak.

Designed for ease of use in the field, the L-Tek P100 features an integrated display that provides real-time gas concentration readings, allowing operators to quickly pinpoint the location of methane emissions. Its long-range detection capability improves survey efficiency, enabling larger areas to be covered in less time while maintaining high levels of accuracy.

The instrument also supports data logging and reporting capabilities, helping organisations maintain detailed inspection records and demonstrate compliance with environmental and safety requirements. By capturing methane readings and associated survey information, operators can track emissions over time, verify the effectiveness of repair activities, and support leak reduction programmes.

The L-Tek P100 is ideal for use across natural gas distribution networks, industrial facilities, utilities, and environmental monitoring applications, providing a practical solution for methane leak detection, emissions management, and asset integrity programmes.
