Full range measurements Ease-of-use means you get everything you need in one exposure, with one sensor – automatically. The RaySafe X2 offers sensors for R/F, MAM, CT, Survey, and even light applications. Choose the sensors you need and add the ones you will need at a later stage. The X2 sensors are made without the need to select ranges or special modes. Most sensors also measure waveforms that can be analyzed directly on the base unit.
