Calibration & Service

S.e. International Offers Calibration & Services

Our radiation detector calibration service offers a calibration reminder service, industry leading support, and speedy turnaround times. We recommend that your instrument be calibrated annually from the date it was placed in service. However, certain industries or applications may require them more frequently.

Calibrations on a new instrument purchase is $70US. If you need an NIST calibration on your new Radiation Alert® detector, please be sure to mention it when ordering to get the discounted rate.

Annual calibrations are $97.68US each. Calibrations with before & after data are $137.19US each.  These prices include Tennessee taxes and a new battery.  A new battery will be installed with every calibration.  Shipping charges are additional.  Any necessary replacement parts under $40US used to ensure proper calibration will be replaced automatically and charged to your invoice.
