3-Channel Dataloggers

Quanterra Q330

Q330's are typically used for broadband standalone and telemetered real-time data recording. They have an external storage device (either hard drive or USB flash drive) and lend themselves for a variety of telemetered modes.

Reftek RT130

RT130's are used for both short period and broadband experiments. Although the RT130 is capable of telemetry, it excels at on-site storage with two compact flash cards and simplicity to setup.
