GENERAL DESCRIPTION
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.
The LASER ONE also offers a rapid response time, improving the efficiency and saving time. The
exceptional reactivity of the LASER ONE laser technology provides excellent results during field scans for
traces of methane. The noteworthy combination of high sensitivity and rapid response deliver
outstanding measurement quality.
The LASER ONE has the user definable option to switch between ‘Absolute’ and ‘Relative’
measurements, the ‘Absolute’ setting will include the background Methane level or the ‘Relative’ setting
will remove this background level from the subsequent reading (see section 7.1.2).
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.
LASER ONE exists in an ATEX version and has been certified with the intrinsic safety protection mode
and has obtained the following marking:
