We look forward to serving you! Calibration & Service The Radiation Alert® Radiation Survey Meters come with a certificate of conformance from the factory (Typically ±15%) and hold a steady calibration. It’s generally recommended your instrument be calibrated annually from the date it was placed in service, but certain industries or applications may require them more or less frequently. If you want to include a NIST Source Calibration (±10%), please be sure to request one when purchasing a new unit. To have your radiation detector calibrated, please visit our Calibration and Service page for instructions and contact information. Our Calibration Service includes: Unit Operational Analysis, Certificate of Calibration with all applicable data NIST traceable Calibration (Calibrated using a Cs137 (662keV) beam calibrator Conforms to ANSI/NSC SLZ540.1.1994 and ANSI N323-1978.
