The FIDELIS is a next generation radionuclide calibrator with unsurpassed accuracy and traceability, and enables rapid, demonstrable compliance with NPL good practice guidance on the assay of radiopharmaceuticals.

The instrument uses our own high resolution, high linearity ‘PAM Electrometer Module,' in conjunction with an ionisation chamber designed at the National Physical Laboratory (NPL). The friendly user interface makes it well suited for use as a reference instrument - to assay samples for calibrating other radionuclide calibrators, thus saving money on calibrators and reference sources.The FIDELIS fully certified Secondary Standard ionisation chamber is an identical version of the national standard chamber held at NPL. Each chamber is tested against the master chamber using a range of radionuclides before delivery. The flexible software makes it very easy to update calibration factors for the instrument using data published by NPL.

  • Secondary Standard Radionuclide calibrator with full traceability to the UK national standards maintained by NPL.
