Plus•X series instrument, 4-parameter, 5,000 m housing

Product no:

The Plus•X four-parameter logger is ideal for profiling and multi-parameter studies. Two primary and two secondary Xchange™ sensors can be utilised at once. Plus•X includes a shackle and sensor cage and comes with data cable and shipping case. Housing rated to 5,000 metres. Xchange™ sensors must be ordered separately. Maximum depth 5,000 metres.

Plus•X is a logger that allows you to change the instrument’s sensor load, in-the-field and on-demand. With Plus•X, your CTD can become an SVTP; shallow pressure sensors can be swapped for deep; and temperature range can be extended or tightened as needed.

One single logger meets multiple deployment requirements.Like all other X•Series instruments, Plus•X uses XchangeTM field-swappable sensors, now available for conductivity, sound velocity, temperature, pressure, and turbidity. 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 – ensure 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.

Plus•X offers high-speed 25Hz sampling, ensuring excellent data resolution. Plus•X also includes a deployment shackle and sensor cage, and can be ordered with additional analog or digital channels for use with 3rd party sensors.


  • Greater return on investment: Each instrument can multi-task as CTD or SVTP, at multiple pressure ranges, assuring greater usage
  • Right instrument always ready: Calibrated sensors are shared amongst all X•Series instruments, ensuring that the right instrument is always field-ready. 
  • Reduced downtime: Recalibrated sensors sent to the instrument means the instrument never leaves the field for recalibration. 
  • Reduction in transport and logistics costs: Instruments can be recalibrated without return to a calibration centre. 
  • Greater system redundancy: Mobility of sensor-heads and modularity of instruments minimizes the risk of downtime on the vessel. 
  • Streamlined management: Less time spent administering instrument recalibration and certification requirements.
