The CTD48 is a small and handy micro processor controlled multiparameter probe for accurate measurements of pressure, temperature and conductivityThe probe is especially designed for limnological measurements on lakes rivers and estuarys but can be used also in shallow water and in the oceanographic range up to 2000 m depth. The probe is equipped with a 4 channel 16 bit data acquisition system of high long-term stability which meets the  high  precision requirements necessary for oceanographic measurements.

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.
