Area Meter Connectivity with Windows® 7

March 21st, 2012

Some customers have inquired if the Windows® Interface Software that accompanies our area meters will work with Windows® 7. Even though Microsoft® developed this operating system years after the LI-3000C Portable Area Meter and the LI-3100C Area Meter were launched, these two instruments still operate as usual with version 1.0.0 of their respective interface programs….

Closing the Methane Gap: Scaling up from the ecosystem to the globe

March 13th, 2012

Direct measurements of methane flux from wetlands are critical to our understanding of the global methane cycle. Due to the difficulty of deploying sophisticated sensors in wetlands, however, these data have been collected from relatively few locations around the planet. Nevertheless, they are are needed to improve global climate models. Dr. Karina Schäfer, Assistant Professor…

The LI-8100A in Action

March 8th, 2012

David Godwin, a PhD Candidate at the University of Florida recently posted a short video on YouTube entitled, Tall Timbers Soil Carbon Respiration Sampling. The video shows the LI-8100A being used to sample soil carbon respiration rates at one of the Stoddard fire plots at Tall Timbers Research Station in Leon County, Florida.

LI-6400XT System Tech Tip: Dealing with Large Moist Samples

February 28th, 2012

With large chambers such as the 6400-24 Bryophyte Chamber, the 6400-05 and 6400-22 Conifer Chambers, or a large custom chamber, it is possible to measure large samples. An advantage of large samples is that larger CO2 differentials are possible, even at lower photosynthesis rates, leading to higher precision in the photosynthesis measurement. With large moist…

Adjusting the LI-8150 Flow Rate

February 15th, 2012

First generation LI-8150 multiplexers, which used a rotary vane pump, provided an adjustable flow rate of 2 to 4 LPM. This functionality was lost when the LI-8150 was upgraded to the more rugged diaphragm pump. However, control over the multiplexer flow rate can be restored through a simple hardware modification. This is accomplished by replacing…
