requirement is for Opaque Long-Term Chambers compatible with a LI-COR Multiplexor.Basic Characteristics:• 48.3 cm L × 38.1 cm W × 33.0 cm H Chamber Dimensions• 3955 cubic centimeter Chamber Volume• 317.8 square centimeter soil area exposed.
The United States Department of Agriculture intends to contract with LI-COR, Inc. on a sole source basis for Long Term Soil Gas Flux Chambers to support ongoing ARS research projects. The type of equipment specifically needed for this requirement cannot be changed without risk to continuity of research. Any response to this notice must show clear and convincing evidence that competition would be advantageous to the Government.
SOIL FLUX CHAMBER Solicitation ID/Procurement Identifier: 68HE0B24P0329 Ultimate Completion Date: Wed May 01 17:00:00 GMT 2024
Supply purchase of a rack-mount, real-time methane/carbon dioxide/water vapor analyzer, multiplexer, and air pump for quantifying air concentrations in flux chambers and animal respiration chambers. Manufactured by netMercury.
LI-COR is, to the USGS' knowledge, the only source who has the equipment is needed to use in conjunction with the USGS soil CO2 flux system.Included unique qualities such as patented pressure vent that allow chamber pressure to track the ambient pressure under calm and windy conditions and minimizes pressure pulses at chamber closing, CO2 flux rate calculated at the CO2 concentration of the surrounding ambient air, a chamber design which provides
