The AML-6 series of instruments is a highly configurable family
of multiparameter sondes designed for a wide range of data
collection applications. The ‘6’ designation refers to the number
of X2 series sensors that may be simultaneously installed on
the instrument’s endcap. Additional sensors may be connected
externally, allowing up to 8 sensors in total.
The AML-6 comes in the AML-6 LGR and the AML-6 RT. While
nearly identical in size and form factor, the two configurations
differ in a few key features which specialize them for their
• The LGR designation (ie. AML-6 LGR) are self-powered via a
rechargeable internal battery and have a mechanical on/off
switch adjacent to their shackle. These instruments are most
commonly used for multiparameter profiling applications and
internally log sensor measurements and transfer data postdeployment.
• The RT designation (ie. AML-6 RT) stream data while in-situ
(though they have the ability to internally record data as well).
Power and communication to these instruments is facilitated
via a waterproof connector located adjacent to the shackle.
These instruments rely on external power for operation and
the application of this power turns the instrument on in lieu of
a mechanical switch These instruments are commonly used in
moored applications, buoys, underwater observatories, and
