SEM5000 Surface Emissions Monitor
GENERAL DESCRIPTION
The SEM5000 is a digital gas detection instrument from QED Environmental Systems, Inc. The
intended use of the SEM5000 is the measurement of low concentrations of methane in the
field (Landfill surface emissions monitoring, leakage surveys of natural gas networks, control
pinpointing outside buildings, quantifying methane fluxes, and laboratory applications for gas
analysis).
The instrument is selective exclusively to methane, thanks to the patented Laser technology
inside. The SEM5000 delivers reliable and accurate measurement of methane concentrations,
even if 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). Thanks to its
metrological sensitivity, accuracy, stability and response time, the SEM5000 is the perfect
instrument for the detection and quantification of methane emissions.
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 SEM 5000 exists in 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 environment the user must take care of the following standards EN 1127-1:2011
(Explosive atmospheres- Explosion prevention and protection - Basic concepts and
methodology) and CLC/TR 50404:2003 (“Electrostatics Code of practice for the avoidance of
hazards due to static electricity”).

USING THE SEM5000
Turning the instrument ON
Press and hold the ON/OFF button for few seconds, until the display is activated.
The start-up sequence includes several steps:
The Landtec Logo is displayed
Information about the version of the instrument firmware, serial number of the instrument,
next recommended calibration date is displayed
NOTE: If there is existing data stored in the instrument’s memory from a previous survey,
the message “DATA TO DOWNLOAD” will appear at the bottom of the screen.
The instrument will warm up. The warm up lasts approximately 20-30 seconds.
NOTE: The instrument’s functions are not available during the warm up period.
Once the warm up and calibration are complete, the four LED lights will blink and the alarm
will sound
A concentration level will be displayed. This is the actual measurement of methane in the
atmosphere. Naturally occurring methane levels in atmosphere are typically 2.5ppm
The SEM5000 is now ready to operate
