25-Channel Solid State Multiplexer - AM25T

Campbell Scientific - The AM25T sequentially connects up to 25 thermocouples or other low-level voltage output sensors to a common differential channel.

The output from this channel is wired to a differential input channel on the data logger.

As the AM25T sequentially changes channels, the data logger measures the output from each thermocouple in sequence.

Type T, E, J, and K thermocouple measurements are standard; other thermocouple types are also supported (depends on data logger model and operating system).
