Our NRC certification certifies your Geiger counter has passed ANSI-STD N323A calibration using a NIST traceable source from an independent US licensed laboratory conforming to United States Nuclear Regulatory Commission NRC regulations 10-CFR-34 and 10-CFR-35 standards.
Manufacturers want to compete on price, not on our certified ANSI-N323A calibration accuracy.
Don't believe a manufacturer's unproven claim of accuracy.
Passing a ANSI-STD N323A calibration, certifies Geiger counter is suitable for regulatory inspections.
