Greenhouse Gas Analyzer (CH4,CO2,H2O)-Ultraportable

Greenhouse Gas Analyzer Ultraportable

LGR’s new ground-breaking Ultraportable Greenhouse Gas Analyzer (UGGA) reports measurements of methane, carbon dioxide and water vapor simultaneously in a package that is compact and crushproof. Small enough to be carried on-board aircraft (TSA approved size) and requiring only 70 watts, the UGGA travels anywhere, initiates data collection within 100 seconds after power up, may be operated wirelessly with an iPhone or Tablet, and opens up new opportunities to measure GHG everywhere.

As with all LGR instruments, the UGGA is simple to use which makes it ideal for field studies, compliance monitoring, leak detection (e.g., natural gas, coal seam gas, coal bed methane), air quality studies and soil flux studies, and wherever simultaneous measurements of methane, carbon dioxide and water vapor are needed. (For details of major advantages, please see:

In addition, the UGGA reports and stores all measured fully resolved absorption spectra which allows the instrument to accurately correct for water vapor dilution and absorption line broadening effects and thus to report CH4 and CO2 on a dry (and wet) mole fraction basis directly without drying or post processing.

Furthermore, LGR’s new “Extended Range” option provides accurate methane measurements at levels up to 10% mole fraction (without dilution) without reducing precision and sensitivity at typical ambient levels - a unique capability to LGR. Moreover, only LGR’s analyzers provide reliable guaranteed measurements at mole fractions more than 20 times ambient levels.

For simultaneous, reliable and accurate measurements of nitrous oxide (N2O) and/or carbon monoxide (CO), without cross interferences, LGR now offers our N2O/CO Analyzer in a portable package ( Similarly, for simultaneous, reliable and accurate measurements of ammonia, methane, carbon dioxide and water vapor, LGR now offers our Soil Gas Analyzer (

LGR’s patented technology, a fourth-generation cavity enhanced absorption technique, has many advantages (simpler, easier to build, rugged, less expensive) over older, conventional cavity ringdown spectroscopy (CRDS) and direct absorption techniques. As a result, LGR Analyzers provide higher performance at lower cost.

LGR Analyzers have an internal computer (Linux OS) that can store data practically indefinitely on a hard disk drive and send real time data to a data logger via the digital (RS232), analog or Ethernet outputs. In addition, LGR analyzers may be controlled remotely via the Internet. This capability allows the user to access and operate the analyzer using a web browser anywhere. Furthermore, remote access allows full control of the instrument and provides the opportunity to obtain data and diagnose the instrument operation without being on site.

Quite simply, no other analyzer provides higher performance. (For details, please see:
