3 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:
II 2 G Ex ib op is IIB T3 Gb -25°CTA+50°C
In hazardous environments, the user must adhere to the EN 1127-1:2019 (Explosive atmospheres.
Explosion prevention and protection - Basic concepts and methodology) and the CLC/TR 50404:2003
“Electrostatics Code of practice for the avoidance of hazards due to static electricity”.

Description of the pneumatic circuits
The LASER ONE samples using a membrane pump. The typical flow is 0.8 l/m and the minimum flow
is 0.7 l/m.
The use of accessories, such as the probes can slightly reduce this flow. It is advised to only use the
parts and accessories supplied by QED Environmental Systems Limited.
The sample inlet port is suitable for a tube with the dimensions ID2mm X OD4 mm.
An internal hydrophobic filter protects the device against any ingress from dust or water. An
additional external filter is also recommended which can help protect the internal filter.
Warning The Hydrophobic filter is not design to filter anything other than water
or moisture; chemicals may damage the efficiency of the filter.
Please be vigilant when completing a survey and avoid sampling dust
and moisture, as if the filter is too saturated it, may result in serious
damage to the internal sensors.
Malfunction of the pneumatic circuit / Pump OFF
The instrument detects when the pump flow is within normal
operating parameters.
If the flow reduces below certain limits, the pump will stop, the
LEDs will light up, the pump icon will have a ‘X’ overlay and the
message "PUMP ERROR" will be displayed.

To toggle the sample pump between its ‘on’ and ‘off’ state, press
the Function button.
When off, the pump icon will have a ‘X’ overlay and the main
display (and ‘%LEL’) will show four horizontal lines.
Warning
The ingress of water or impurities may cause
the
malfunction of the
pneumatic circuit and in some cases the damage to the sensors.
Warning
If the sampling is interrupted or suspended by the pump being turned
off, the instrument will stop logging and horizontal lines (" - - -") will
appear adjacent to the memory capacity percentage.
Restarting the pump operation
To turn the pump ON, press the Function button, the pump will restart and the ‘X’ overlaying the
pump icon will dissapear.

7 SETTINGS
Measurement Range
Methane measurement
The LASER ONE measurement will be displayed on the main screen
The LASER ONE measurement is selective to Methane only and will not suffer from any cross-gas
contamination from other gases due to the Laser Diode technology used.
The dual range will display the measured Methane from 0-1% in ppmVol (0- 10,000ppm) and above
1% will automatically switch to display the measurement in %Vol up to the full-scale of 100%.
Measure in absolute mode (ABS) and relative mode (REL)
The ‘Absolute’ measurement (ABS), is the measurement of the ambient concentrations which will
include the background level of Methane present in the atmosphere, this is typically between 1.0
and 3.0 ppm.
It may be desirable for the user to remove this background level of Methane during the
measurement survey. The ‘Relative’ measurement (REL) allows for the user to see more easily a
change in the environmental concentration, it may also make a transient leak of gas more visible to
the user as it would act as a contrast between the ambient concentration and the magnitude of the
leak.
When the instrument is in ‘Relative’ (REL) mode, if the detected measurement exceeds a pre-defined
value of 5ppm, the instrument will automatically switch to ‘Absolute’ (ABS) mode. When the
measurement returns to a lower value (i.e. <5ppm), the instrument will automatically switch back to
‘relative’ (REL) mode.
Note: The configuration or settings of the instrument when it is turned off will be remembered
and returned to automatically when next used.

power supply (Code 423007). Connect the charger with the power supply according the figure below, using
the two polarity connectors in conformity with the maximum authorized voltage Um equal to 15V.
The battery charge cycle typically takes 4.5 Hrs, a red led will be on during the charge cycle which
when complete will change to green to indicate a full charge. The battery level indicator on the
LASER ONE consists of three segments, the last of which indicates that there is approximately 30
minutes of power remaining.
The typical operational time from a full charge is 10 hours at an ambient temperature of 20°C and
with the backlight ON.
Advice about the use of lithium ion technology:
In order to optimize the use and the lifetime of your battery, please, follow the following guidelines:
Charge the battery with a temperature between the range [+10°; +30°C]
