AML Base•X

Entry Level Logging Profiler

Base•X is a rugged, shallow water logging instrument. Designed for profiling in coastal waters, the instrument includes a shackle, a sensor cage, and an LED status indicator to simplify deployment preparation. Highspeed 25Hz sampling ensures excellent data resolution. Base•X’s compact size and compatibility with AML’s Xchange™ sensor-head architecture make it the ideal companion for the shallow water hydrographic surveyor.
Like all other X•Series instruments, Base•X uses Xchange™ field-swappable sensors. Base•X is available for use with conductivity, sound velocity, temperature, pressure, and turbidity Xchange™ sensors. This means that sensor heads can be shared with other instruments, regardless of instrument size or type.

Total flexibility – of instrument model, of sensor type, and of sensor range – ensures that the right instrument is always available. Field-swappable sensors also streamline recalibration: instead of sending the entire instrument back to a recalibration centre, calibrated sensor-heads can be sent to the instrument. Changing sensors is easy: simply unscrew one sensor-head and replace it with another.

Available Sensor-Heads

X•Series instruments are compatible with our Xchange™ sensor-heads:

Sound Velocity: SV•Xchange™
Conductivity: C•Xchange™
Temperature: T•Xchange™
Pressure: P•Xchange™
Turbidity: Tu•Xchange™
Sensor-heads are ordered separately. Read more about compatible sensors here:  AML Sensors
