  • Product Description

    The Prospector, comprised of the Model 3007A Traditional Geiger Counter configured with the Model 3012 External Standard Probe, was originally designed for civil defense use, but also has general purpose use. 

    The base unit of the Model 3007A itself is a portable, hand-held survey meter providing three operating ranges reading on a dual scale up to 50 mR/hr or 30,000 CPM.  See the close-up picture below, also noting the battery check feature at the right end of the gauge.

    3007ametertn.jpgThe survey meter incorporates a sealed, splash proof speaker which produces the audible clicks.  The speaker is powered by a separate 9-volt battery and can be turned off in case the meter is inadvertently left on, preserving the other "D" batteries to continue operating the meter itself.

    Although of a traditional design, the Model 3007A Survey Meter is a fully modern unit, with completely redesigned and up to date transistorized electronics, and with calibration at the factory in accordance with industry standards.

    This instrument is shockproof and designed for rugged use, thus perfect for operation in the field.

    stdprobetn.jpgThe Model 3012 Standard Probe, shown cradled in the meter’s handle above, is ruggedly built, consisting of a thick-walled Geiger-Mueller (GM) tube, yet with a sliding window (shown open at left) to provide energy discrimination capability.  The probe's slim design allows it to be easily maneuvered in hard to reach locations.  It measures medium and high energy Gamma and X-rays, as well as high energy Beta radiation.  These design features make it perfect for mineral prospecting.  As shown in the picture at left, the probe includes an integral 3 foot straight cable, terminating in a BNC connector.

    This product typically ships within 2 to 3 business days.  Specify between standard readout in mR/hr and CPM (default), or alternate readout in uSv/hr and CPS.
