PRM-9000 Geiger Counter

Please note that there is an extended lead time on these units. This PRM-9000 Radiation Monitor is identical in most respects to its forerunner PRM-8000, i.e. a Digital Pocket Geiger Counter designed to detect Alpha, Beta, Gamma, and X-Radiation, displaying through a digital readout, and emitting an audible click with each radiation count detected.   But the major difference is that the PRM-9000 has been fitted with a large, pancake-style Geiger-Mueller tube.  This is the same ultra-sensitive detector as used in the Inspector line of instruments. The photo (at right) of the back of the instrument shows the thin mica end window of the GM tube through the protective mesh screen, with a diameter of 45 mm (1.75 in), producing increased efficiency of radioactivity detection, and offering excellent sensitivity to low  levels of Alpha radiation, in addition to normal Beta, Gamma and X-ray detection. This feature makes the PRM-9000 suitable for applications requiring higher levels of sensitivi
