CH4 / H2O Ultraportable Methane Analyser (Model UMA)
LGR’s new Ultraportable Methane Analyser (UMA) reports measurements of methane and water vapor simultaneously in a package that is compact, crushproof and travels anywhere.
Small enough to be carried on-board aircraft (TSA approved size) and requiring 60 watts (on either AC or DC power), the UMA offers opportunities to measure methane anywhere. As with all LGR instruments, the UMA is simple to use and isid eal for field studies, compliance monitoring, leak detection, air quality and soil flux studies, and wherever measurements of methane, carbon dioxide and water vapor are needed.
In addition, the UMA reports and stores all measured absorption spectra which allows the instrument to accurately correct for water vapor dilution and absorption line broadening effects and thus to report CH4 on a dry mole fraction basis without drying or post processing. Furthermore, LGR’s “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 analysers provide reliable guaranteed measurements at mole fractions greater than 100 times ambient levels.

All LGR Analysers now come with a 2 Year Warranty as standard, underlying the quality and robustness of their manufacture and high reliability. Warranties can also be extended to 3 or 4 years at additional cost, at the time of purchase. Please enquire for further details.
Under normal operation and for the vast majority of applications, LGR Off-axis ICOS gas analysers require the minimum of servicing and maintenance.
One of the many benefits of this technology is long-term unattended reliability in the field.
Annual maintenance would normally include an inspection of the internal pump (or external pump if fitted) and the replacement of the pump diaphragm and valve seals if necessary.
This can be carried out by the user themselves or by ET either on site or back in the ET workshop (for a maintenance quote, please contact us).
ET recommends that LGR Analyser users consider the purchase of a field maintenance kit which includes:
- Replacement solid-state hard-drive with LGR operating system and specific system files pre-loaded, for quick and simple swap-out in the field if ever necessary.
- Pump maintenance kit (internal) to include spare pump diaphragm and valve seals.
- Mirror cleaning kit.
Please contact us if you would like to receive a quote for the field maintenance kit.
Additional maintenance will be required for the LGR Liquid Water Isotope Analyser (LWIA) and Auto-injector unit and also the LGR Dissolved Gas Extraction Unit (DGEU).
For these instruments, please refer to the operation manual supplied with these instruments.
