This is the previous generation of GSM-501 MicroR Meters. This unit, in good condition, is on sale. The unit features a 1"x1" plastic scintillation probe, tissue equivalence, analog display, auto-ranging in dose (micro R/hr), integrate mode, peak hold, and audio. You can see photos and a video demonstration of the actual unit. If you purchase the unit, we include a fresh calibration and 90 day warranty. Conditions to be aware of: the unit measures in dose only. This unit will not measure in counts like the new models. The hasps are slightly loose.
