Flux Measurements

More Choices at Great Prices

Los Gatos Research (LGR) now offers more analyzer choices to measure surface-atmosphere fluxes. Traditionally, there are four main flux measurement techniques: Eddy Covariance, Relaxed Eddy Accumulation, Gradient and Chamber-based. Though carbon dioxide and water vapor are the most common greenhouse gases measured, in many ecosystems a number of different gases must be measured. LGR's technology has improved rapidly over the years and new analyzers are now available allowing scientists to expand their research by measuring other greenhouse gases such as methane, nitrous oxide, carbon monoxide, ammonia, and carbonyl sulfide.

Now LGR offers an expanded line of high speed (10 Hz) and lower speed (up to 1 Hz) gas analyzers that can be used for all four techniques to measure a wide variety of gases.

Two important accessories are also available:

Multi-Channel Data Logging Software: Synchronizes serial (RS-232) outputs from multiple LGR analyzers and other devices, such as GPS or sonic anemometers, and records all data with a common time stamp.

Multiport Inlet Unit (MIU): Available with either 8 or 16 inlets and 1 output port which is used to connect to the Analyzer. The MIU inputs are fully controlled by software on the LGR Gas Analyzer so that any port may be selected at any time. Once programmed, the sequence of measurements is fully automated.

Here is a list of the LGR analyzers that can be used for each flux measurement technique:
