Optional accessories may be included with your system. If not, they are available form LI-COR or your distributor.
6400-03 Rechargeable battery
The 6400-03 rechargeable batteries are 12 volt lead acid batteries. Batteries are charged prior to shipping, but may discharge during shipping and storage. It is a good idea to test your batteries to make sure they are charged.
The 6400-03 batteries require the LI‑6020 Battery Charger for recharging. One 6400-03 battery provides approximately 3-4 hours of battery life at 25 °C, depending on pump usage or wireless card usage.
NOTE: There are 2 battery connectors in the case. You can attach a second, fully charged battery before removing the discharged battery to provide uninterrupted operation.
LI‑6020 Battery charger
The LI‑6020 can charge up to four 6400-03 batteries at a time. It is compatible with 115 and 230 VAC main power.
Soil temperature probes
The Omega Soil Temperature Probe (6000-09TC) is a 2-wire thermocouple sensor that can be wired to the auxiliary sensor interface for survey measurements.
- See Connecting the Omega soil temperature probe to connect to the auxiliary sensor interface.
The 8100-203 and 8150-203 soil temperature probe has a 2-wire adapter cable for connection to the auxiliary sensor interface. Alternatively, the connector can be removed for installation into a long-term chamber when using the multiplexer.
- The 8100-203 is a bare wire thermistor used for single-chamber long term measurements. It connects to the auxiliary sensor interface (see Connecting the 8100-203 soil temperature probe).
- The 8150-203 thermistor probe has a plug for direct connection to the 8100-104/C Long Term Chambers when used with the multiplexer (see Connecting the 8150-203 soil temperature probe).
Soil moisture probes
The GS1 Soil Moisture Sensor (Decagon Devices, Inc., Pullman, WA) is a dielectric sensor that measures volumetric water content of the soil.
- The 8100-205 probe has a 3-wire connector for connection to the auxiliary sensor interface on the LI-8100A (see Connecting the GS1 soil moisture probe).
- The 8150-205 probe has a plug for direct connections to the 8100-104/C Long Term chambers when used with the multiplexer (see Connecting the GS1 soil moisture probe).
The ECH2O Model EC-5 soil moisture probe (Decagon Devices, Inc., Pullman, WA) is a dielectric sensor that measures volumetric water content of the soil.
- The 8100-202 probe has a 3-wire connector for connection to the auxiliary sensor interface on the LI-8100A (see Connecting the EC-5 soil moisture probe).
- The 8150-202 probe has a plug for direct connection to the 8100‑104/C Long Term chambers when used with the multiplexer (see Connecting the EC-5 soil moisture probe).
The Delta-T ThetaProbe is a more durable sensor that provides a more precise measurement of volumetric water content.
- The 8100-204 probe has bare wire leads, and is for use with the auxiliary sensor interface (see Connecting the Delta-T ThetaProbe).
- The 8150-204 probe has a connector pre-installed for direct connection to the 8100-104/C long-term chambers when used with the multiplexer (see Connecting the Delta-T ThetaProbe).
8100-104 and 8100-104C conversion kits
The 8100-104 long-term chamber’s opaque “bowl” can be swapped out with the clear bowl used on the 8100-104C long-term chamber (using part number 8100-910), and vice versa (using part number 8100-911). Each kit includes the replacement chamber bowl and all mounting hardware required.
Wireless communications package1
The wireless communications package (part number 8100-565) includes 8100-570 Apple iPod Touch (32 GB), serial cable (part number 392-10587), USB-to-RS232 adapter (part number 6400-27), wireless card (part number 8100-552), and iPod Micro Case (part number 8100-571).
GPS mapping kit
The mapping kit (part number 8100-405) is an accessory for use with the LI-8100A Automated Soil CO2 Flux System when making survey measurements with the 8100-102 or 8100-103 chamber or for continuous measurements. The mapping kit adds geographical data (latitude, longitude, speed, and direction) to observations of soil CO2 flux or CO2 concentration. The mapping kit can be used with the survey chambers to map soil CO2 flux data across the area of interest, or it can be used in a continuous measurement mode (without a chamber) to map CO2 concentrations across a transect.
The mapping kit includes a GPS receiver (part number 9981-185), mounting bracket (part number 9981-211), 12-pin Eurofast splitter cable (part number 392-12388), and spare parts kit (part number 9981-186) with intake tube and connectors. See GPS accessory for details.
