Product no :
The AML-3 series of instruments is a highly configurable family of multiparameter sondes designed for a wide range of data collection applications. The ‘3’ designation refers to the number of sensors that may be installed on the instrument’s endcap. One additional sensor may be connected externally, allowing up to 4 sensors in total.
The AML-3 comes in two depth options: max 500 m and max 6,000 m. Both depth options are available in RT and LGR designations. These differ in a few key features, which specialise them for their respective applications:
  • The LGR designation (ie AML-3 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-3 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.
Typical configurations include:
  • Sound velocity profiling (SVP)
  • Sound velocity and turbidity profiling (SVP Tu)
  • Conductivity temperature and depth (CTD)
  • Sound velocity / conductivity temperature and depth (SVCTD)

Key benefits

  • Three X2 series interchangeable ports: Ability to custom configure a single instrument for multiple applications
