This kit includes four High Range Eberline Model R0-2A Ion Chamber Radiation Detectors.  Items are packed in a “like new” Model 1550 Pelican case (no pull and pack foam insert). These meters were purchased from a government auction and appear to have very little field use. Battery test shows that they work.  They are in “like new ” condition and they are sold “as is”. These meters will need to be calibrated for valid regulatory surveys. Meters can be picked up locally or shipped. Please contact me for additional information.
