With an extended range of -5 to 45 ⁰C and a thin-walled, monolithic titanium tip that enables a fast response time, T•Xchange™ is a high performance temperature sensor in a modular form.

The oceanographic industry’s only field-swappable temperature sensor contains embedded electronics where calibration coefficients are stored. Sensor-heads can be moved from instrument to instrument without impacting field accuracy.
