This pre-owned RO-2S-1 ion chamber is reconditioned and fully functional. It is used for mid-range energy. This rugged ion chamber / survey meter is a quality ion chamber that costs a small fraction of a new unit. The ion chamber features a beta window slide, three ranges of 0-50 mR/hr, 0-500 mR/hr and 0-5000 mR/hr and external calibration pots. The unit operates on three standard 9 volt batteries. This instrument is scratched but functions as well as a new unit. We include calibration and a 90 day warranty. We have never had a return or a complaint on this product. |
