Detect Methane Leaks with the TDL-500 Gas Detector 

Using laser spectroscopy technology, the Geotech TDL-500 can detect methane leaks in a range of applications, from natural gas pipelines to landfill or coal mining sites. The tunable diode laser provides total selectivity to methane with a sensitivity of 1ppm. ATEX certification to Zone 1 means it can be used in most hazardous areas, detecting methane leaks and their location with speed and precision.

The laser technology presents an advantage over FID devices as it does not need a hydrogen gas supply, avoiding transportation of hazardous gases. Fast response times mean less time spent monitoring and GPS is available to record leak position, set up routes and record readings. The TDL-500 offers portable laser leak detection as it is easy to carry for one person to use on foot and can work for 8 hours from a full charge. Users are likely to be involved with natural gas networks, landfill gas surface emission checking, biogas feeds to CHP engines, water treatment plants, momentary methane leak detection and sewerage system methane detection.
