The X•Series makes use of XchangeTM field-swappable sensors. Each XchangeTM sensor-head contains its own embedded calibration, a key part of enabling the sensor to work with any X•Series instrument. It is this embedded calibration - as well as critical electronics components - that ensure that field accuracy is maintained.
Field swappable sensors also streamline recalibration: instead of sending the entire instrument back to a recalibration centre, a calibrated sensor-head can be sent to the instrument. Changing sensors is easy: simply unscrew one sensor and replace it with another.
