The GPS accessory

The optional 8100-405 CO2 Mapping Kit can be used without a soil chamber in continuous measurement mode to map CO2 concentrations across a transect. You can make a single measurement of up to 24 hours. A user-provided intake tube is required; tubing and fittings are provided in the spare parts kit to aid in construction of the intake tube. Considerations and guidelines for sampling height, intake tube construction, and concentration mapping can be found in Application Note #135, entitled “Mapping CO2 Concentrations and Fluxes with the LI-8100A”.
