GCA-07W Digital Geiger Counter



Only NRC Certified Geiger Counters
Give Proven Accurate and Reliable Measurements


Not all Geiger Counters are the same.

Many manufacturers are happy to compete on price, none of them want to compete with us on quality or accuracy.

Why? Because our Digital Geiger Counters are NRC ready to be “NRC Certified” – To be NRC certified our Geiger counters are sent to an independent United States Government licensed nuclear laboratory, where it tested against the strict guidelines and standards of the U.S. Nuclear Regulatory Commission.

NRC Certification tells you the Geiger counter is as accurate as “accurate” can be! With an NRC-certified Geiger counter, your radiation reading reports are authoritative and acceptable to governmental agencies. NRC has an additional charge, see NRC option in buy box below, and adds two weeks to the delivery.



TECHNICAL SPECIFICATIONS

NRC CERTIFICATION READY - NRC certification can only be given by U.S. Government licensed laboratory. The NRC certificate certifies that the radiation reading from the Geiger counter is accurate.
DETECTOR SENSITIVITY: Detects Alpha particles above 3 MeV in energy. GM tube has a thin mica window that allows alpha radiation to be detected. Beta radiation above 50 KeV; X-Ray and Gamma radiation above 7 KeV
COUNTING RESOLUTION AND RANGE: 1 Count Per Minute (CPM) - 10000 Counts Per Second (CPS)
RADIATION RESOLUTION AND RANGE: 0.001 mR/hr resolution / 1000 mR/hr Range (Imperial measurements); 0.01 uSv/hr resolution - 10 mSv/hr range (Metric)
