X•Series is a family of sensor-Xchangeable oceanographic instruments that allows you to change an instrument’s sensor load in the field and on-demand.With an X•Series instrument andXchangeTM field-swappable sensorheads, your CTD can become an SVTP, shallow range instruments can be made to go deep, and temperature range can be extended or tightened as needed.
X•Series lets you do more. All X•Series instruments share a common architecture, so any sensor head can be attached to any instrument, regardless of size or type: real-time probe, vertical profiler, or in-situ logger.

Total flexibility – of instrument model, of sensor type, and of  sensor range – ensures that the right instrument is always available.
