Laser-based gas sensor technology is an effective tool for detecting and quantifying methane emissions. Laser sensors are sharp with a quick response that can detect the relevant gas.

The device is made even easier to use with its integrated camera, so operators can pin-point exactly where the emissions are coming from. A screen recording of the image can be captured, recording the gas concentration, alarm set point and zoom information for further analysis or reporting later.

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.

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.

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.

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.

Bluetooth devices can be paired to a mobile phone so the information can be transferred to an online portal for total data integrity and reporting, as well as capturing location so emissions can be traced to specific locations. This makes it even easier to ensure leaks are traced and any emission preventing actions can be recorded and used to prove their success against the previous emission readings at the same location.

The LaserMethane Smart is a compact, portable methane gas detector, the latest laser methane device, replacing the obsolete LaserMethane mini. LaserMethane Smart can detect methane leaks at a distance up to 30m, enabling operators to quickly survey multiple leak risks, and safely, without having to enter a hazardous area.

OZ Optics’ ER-100 series of polarization extinction ratio meters allows one to quickly measure the output extinction ratio of light from a fiber. A rotating polarizer measures the extinction ratio and the orientation of the transmission axis with respect to the key on the connector. As an option, neutral density filters can be added to the ER-100 extinction ratio meters to extend the maximum power range. These filters can be easily inserted and removed without disturbing your setup and allow power levels up to 2 W to be measured. The ER-100 meters operate in several modes. In real time mode, the meter gives the extinction ratio and alignment. In logging mode, the meter gives the worst-case extinction ratio over a given time span. This mode is ideal for QA measurements. In addition, the meter can provide a relative power readout, proportional to the input power in dB. This readout is updated at up to 650 times per second. The computer interface allows the unit to be used with computer control units, for alignment purposes. The combination of polarization and relative power functions allows the unit to be used for complete auto-alignment of polarization maintaining components. Key Features:
