The SEI Inspector USB, The SEI Inspector Xtreme USB, and The SEI Inspector EXP radiation survey meter support.
The function, settings, and menu operation of the latest SEI Inspector models is identical. However, the SEI Inspector EXP has a detector in the probe handle at the end of a one meter cable instead of in the main body of the meter, like the SEI Inspector USB and SEI Inspector Xtreme USB.
