Calibrating the LI-7000 for H2O

Calibrating the LI-7000 for H2O

To calibrate the LI-7000 CO2/H2O Analyzer for water vapor, LI-COR recommends using our LI-610 Dew Point Generator. The LI-610 generates a known water vapor concentration and reports the dew point value on the front LCD display in units of Degrees C. The gas stream can then be plumbed directly into the LI-7000’s appropriate inlet port. If using the LI-7000 Windows Interface Software, it is very simple…

Conserving Power with the LI-8100/8150

Conserving Power with the LI-8100/8150

Researchers often want to set up the LI-8100 Analyzer Control Unit and LI-8150 Multiplexer to collect soil CO2 flux measurements over an extended period of time, with several Long Term Chambers in operation. While this system is designed to operate with AC power, LI-COR realizes this is not always available in remote locations. To solve this problem, many researchers utilize a combination of solar panels and batteries. If the…

Powering the LI-1400 with an External Power Supply

Powering the LI-1400 with an External Power Supply

To power the LI-1400 Datalogger with an external power supply, use either the 1400-301 Terminal Block or a custom power adapter. If using the Terminal Block, power can be supplied from the 1400-402 External Battery Pack, the 1400-401 AC adapter, or a user-supplied power source. Connect the power supply by attaching the red (+) lead to the connection…

LI-COR Photosynthesis System

Antarctic Experiments Include the
LI-COR Photosynthesis System

The middle of austral summer, when high temperatures are around 33°F, is a perfect time to explore the biology of Antarctica’s McMurdo Dry Valleys, according to Dartmouth College post doc Becky Ball. For the last several years Dr. Ball has spent the months of December through February at the McMurdo Dry Valleys Long Term Ecological Research site, where the landscape looms large, but a 1mm nematode sits at…
