10 Using the LI-8150
Multiplexer
About the LI-8150
The LI-8150 Multiplexer is an accessory for the LI-8100A that makes it possible to
connect as many as 16 individual chambers at one time, which are sampled and
controlled by the LI-8100A Analyzer Control Unit.
The LI-8150 expands the capabilities of the LI-8100A and provides a simple
solution for spatial and temporal sampling. The LI-8150 allows the researcher to
control the number of chambers needed for the study and offers the flexibility of
adding more chambers as needed. The LI-8150 is constructed with the same
attention to detail as the LI-8100A, and features a number of innovative design
details:
Choose from 8 or 16 port configurations – 8-port system can be easily
upgraded to 16-port system
Durable, weatherproof connectors and case
High flow, low power, long-life solenoid valves
Filter assemblies clean incoming air
LED indicator panel provides Multiplexer diagnostic information
System software for leak testing without the need for additional hardware
The LI-8150 can also be connected to ordinary gas sampling lines for vertical
profiling, custom chambers, or other studies. A 15 m extension cable can be
connected to each soil chamber to provide a measurement diameter of 30 meters.

diameter of up to 30 m.
