The LASER One is a professional instrument for the detection and localization of methane gas leaks, it is selective and it requires no gas cylinder. Suitable for the detection of leaks in underground and above ground pipelines. The instrument can be used for better quantification of CH4 (methane) emissions from infrastructure and has great results even with biogas leaks in the biogas plants, thanks to the high precision of LASER technology. Equipped with GPS antenna and Bluetooth for data transfer from the instrument to a PC or PDA.
