This is a used RI-101 with less than 5600 hours on the lamp and the detector. The detector has a new purge valve and new fuse holder. There is some very minor damage to the outer case but this is minimal and does not affect the performance of the detector. Please see photos. If you require a back-up for your present RI detector, this one would be perfect! Comes with a 6 month warranty.
