The LASER ONE is a digital gas detection instrument manufactured by QED Environmental Systems Ltd. The intended use of the LASER ONE is to measure low concentrations of Methane in various applications (leakage survey of natural gas networks, control pinpointing outside buildings, quantifying Methane levels and laboratory applications for gas analysis).

The LASER ONE instrument has selective measurement of Methane due to the Laser technology used. The LASER ONE delivers reliable and accurate measurements of Methane concentrations, irrespective of whether the sample contains other gases or hydrocarbons. Due to its lightweight design and modest size, LASER ONE can be easily transported and is ideal for measuring Methane concentrations in the field (landfills, site investigations or gas networks).

Its capability to measure from lower concentrations to higher concentrations changing between ranges rapidly, makes LASER ONE the appropriate instrument for the detection of leaks from gas meters and the gas distribution network and also as an analyser for the quantification of gas emissions. Thanks to its metrological sensitivity, accuracy, stability and response, LASER ONE is particularly suited to any application requiring the measurement of Methane concentrations in sampling mode or in line (option). The single-dial function selector makes the LASER ONE easy to use and the large, back-lit LCD display provides easy to read menus and results. The LASER ONE has a measuring range covering 0 to 1,000,000 PPM (part per million) or 100% Methane concentration.

LASER ONE is equipped with an integral GPS device and the capability to record locational data to compliment measured gas analysis results. This makes LASER ONE an accomplished instrument to work conveniently in the field with efficient results.
