R3 and HS Sonic Anemometer Configuration

R3 and HS Sonic Anemometer Configuration

The Gill R3 and HS series of anemometers can be connected to the LI-7550 to collect data on a USB drive.  This can facilitate remote data monitoring and collection through the available Ethernet connectivity.

The anemometer will have to be preconfigured to send data out in the required format. This can be achieved using any serial communication software like Windows HyperTerminal or Tera Term (which can be downloaded for free here). You can also use the WindCom or RCom2…

Using the LI-6800 in Undergraduate Environments

Using the LI-6800 in Undergraduate Environments

Dr. Jason Kilgore, an associate professor of biology at Washington & Jefferson College, has been using top-notch research instrumentation to enhance undergraduate learning. As a member of the Ecological Research as Education Network (EREN), which is a collaborative network of schools that are primarily undergraduate institutions, Dr. Kilgore and other EREN faculty “use authentic research as a model for students to learn about biology.” He does so by incorporating an LI-6800 Portable Photosynthesis System into his coursework and student research.

7200-101 Flow Module – High Frequency Noise Reduction

7200-101 Flow Module – High Frequency Noise Reduction

In some situations, the 7200-101 Flow Module may emit high frequency noise through its exhaust port. This may occur if the motor drive of the Flow Module is ramped up to maintain the flow rate as pressure drops in the flow path.

Inline filters that clog up over time may cause a significant motor drive increase, especially if the inline filter is not replaced before the motor drive reaches its maximum at 100%.

The Power of FV2200

The Power of FV2200

Leaf Area Index (LAI) measurements, such as those taken by the LAI-2000 or the LAI-2200/C, can be used to determine treatment effects, crop progression, and seasonal variation, to name a few parameters.

The process of obtaining LAI measurements can be very simple.  To generate a value for LAI, take a series of Above and Below canopy readings, repeating as many times as needed to develop statistical robustness.   The process of interpreting them, however, can be more complex.

FV2200 has many…

Upgrading the Wheels on the LI-6800 Travel Case

Upgrading the Wheels on the LI-6800 Travel Case

The LI-6800 travel case is a vast improvement over the case offered with the LI-6400/XT. One of the major changes in the case is that it has wheels, making it very easy to transport the instrument. For most users, the stock wheels on the case will perform well and last a long time. However, for users like the Field Application Scientists at LI-COR who put many more miles on the case than a typical user, the stock wheels just don’t…
