NIST Certificate of Traceability

FLIR's exclusive 12-Point Inspection and Calibration Program uses temperature references that are calibrated annually and traceable to the SP Technical Research Institute of Sweden, and the National Institute of Standards and Technology (NIST).

12-Point Inspection and Calibration Program:

  • Perform a complete operational check
  • Image calibration and camera alignment, when applicable
  • Verify all internal cable and PCB connections
  • Upgrade internal camera software to latest revisions
  • Perform minor repairs
  • Verify and/or calibrate IR image as needed each temperature range for image uniformity
  • Verify ambient temperature compensation as needed
  • Re-calibration to ensure it meets factory specification
  • Perform quality approved acceptance test procedure
  • Provide certificate of conformance
  • Provide calibration certificate (optional, extended calibration certificate with measured values)
  • Clean optics; viewfinder cleaned when applicable
  • *Does not include parts or labor required to meet calibration standards, nor additional lens/filter calibrations.
