Landtec GEM™5000 Landfill Gas Analyzer
The Landtec GEM™5000 monitors Landfill Gas (LFG) collection and control systems by sampling and analyzing the methane, carbon dioxide and oxygen content of landfill gas. Some models also include carbon monoxide and hydrogen sulfide analysis options (listed below).
- Measures CH4, CO2 and O2 volume, static pressure and differential pressure by percentage
- Calculates balance gas, flow (SCFM) and calorific value
- Fast and accurate measurement
- Light and compact structure
- Certified intrinsically safe for landfill use
- Calibrated to ISO/IEC 17025
- CO and H2S detection (on Plus models only)
- 3-year warranty with optional service plan
- Annual recommended factory service
- Available with GPS and additional gas detector
- Designed specifically for use on landfills to monitor landfill gas (LFG) extraction systems, flares, and migration control systems
- No need to take more than one instrument to site
- Can be used for monitoring subsurface migration probes and for measuring gas composition, pressure and flow in gas extraction systems
- The user is able to set up comments and questions to record information at site and at each sample point
- Ensures consistent collection of data for better analysis
- Streamlined user experience reduces operational times
- Remediation - Site investigation and clean up
- Remediation - Site investigation and clean upWaste to Energy - Gas field balancing and maximizing gas production
- Environmental Compliance
- Landfill Gas Collection & Control Systems
- Landfill Gas to Energy
- Subsurface Migration Probes
Not necessarily. When the H2S sensor is exposed to high levels of H2S gas, it is recommended to run the instrument with the gas pump on with ambient air for the same amount of time the sensor was exposed to the high level of H2S. This allows for purging of the instrument before turning the instrument off. Be aware though that continued exposure to levels over 5000ppm H2S will damage the sensor.
Exposure to H2S levels from 2000-5000ppm with moisture will degrade the sensor more quickly. Using filters inline reduces the moisture content of the gas stream entering the instrument.
A common cause for lower than expected gas readings is leakage in the instrument. Perform a leak test by connecting the Condensate Separator Tube to the Pressure Connection 1 Port with tubing.
Perform a leak test as described in the User Manual Optima 7 Biogas. If the leak test fails, check for defective or missing o-rings in the Condensate Separator Tube.
If the user uses the Sampling Probe with sampling lines to take gas readings, place a clean Leak Proof Test Cap on the end of the probe spike. Attach the other end of the sampling line onto the Condensate Separator Tube. Perform the leak test. If the leak test fails, check for defective or missing o-rings in the Condensate Separator Tube and for cracks in the sampling line.
Look closely at the prongs of the thermocouple. The prongs might be dirty. Use a sponge soaked in a 1:3 vinegar/water solution and gently wipe the prongs. Wipe dry with a lint-free cloth or allow to air-dry.
Simultaneously, press the ESC key and the power button then release both keys. You will have to update the Date and Time setting in your instrument afterwards.
