Prior to delivery, each Gamma-Scout® undergoes a rigorous factory inspection and calibration protocol. We use a highly stable G-M tube, so it is unlikely your Gamma-Scout® will require calibration during the first 5 years of service. After that, should you desire a factory calibration and test, just return the unit and we will happily check and recalibrate your unit for a modest processing charge.

Please note: The rules of ISO certification for commercial use require calibration of all equipment after 2 years of use. We offer 2 options (both subject to a fee) – a major or minor calibration (see user handbook).
