3GENERAL DESCRIPTION
The SEM5000 is a digital gas detection instrument from QED Environmental Systems
Ltd. The intended use of the SEM5000 is the measurement of low concentrations of
Methane in various applications (Landfill surface emissions monitoring, leakage surveys
of natural gas networks, control pinpointing outside buildings, quantifying methane
fluxes, and laboratory applications for gas analysis).
The SEM5000 instrument has selective measurement to Methane due to the Laser
technology used. The SEM5000 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, the SEM5000 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
SEM5000 the appropriate instrument for the detection of leaks from Landfill gas
applications and also as an analyser for the quantification of gas emissions. Thanks to
its metrological sensitivity, accuracy, stability and response, SEM5000 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 SEM5000 easy to use and the large, back-
lit LCD-display provides easy to read menus and results. The SEM5000 has a measuring
range covering 0 to 1,000,000 PPM (part per million) or 100% Methane concentration.
The SEM5000 also offers a rapid response time, improving the efficiency and saving
time. The exceptional reactivity of the SEM5000 laser technology provides excellent
results during field scans for fugitive traces of Methane. The noteworthy combination of
high sensitivity and rapid response deliver outstanding measurement quality. The
SEM5000 is provided with integral GPS and Bluetooth, eliminating the need for
additional devices. The internal memory is capable of storing up to 48 hours of scan
data.
The SEM5000 is the perfect, easy-to-use instrument for accurately measuring and
recording Methane concentrations during surface emissions monitoring.
The SEM5000 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°C≤TA≤+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”.

5INSTRUMENT FUNCTIONS
Switching the instrument ON and OFF
Switch ON
Press the ON/OFF button for a few seconds, until
the display is activated.
The start sequence includes several steps:
-Geotech logo.
-Firmware version of the instrument, detector
board information, instrument serial number
and next service/calibration date.
-Current date / time and next calibration.
If there is data stored in the instrument, you will see
the message "DATA TO DOWNLOAD". In order to
download the data, the ProSoft software must be
used.
The instrument will warm up and self-calibrate. The
warm up will last approximately 20-seconds and
during this time, the instrument’s functions are not
available for use.
Once the warm up and calibration are complete, the
four LED lights will blink and the alarm will sound.
The SEM5000 is now ready for use.
Switch OFF
To switch off the instrument, press and hold the
ON/OFF button for a few seconds. A shut off
message will appear on the display and a timer will
count down. Once the counter starts to count down
the button can be released.
