Certificate of Calibration
Calibration is carried out under a xenon arc light beam, at normal
incidence to the sensor, by reference to transfer standards.
Individual Calibration Certificates and spectral response graphs are
supplied with each UV3p sensor. The following details are included.
Example
CERTIFICATE OF CALIBRATION
The Manufacturers hereby certify that this instrument has been calibrated
using standards whose accuracy is traceable to the National Physical
Laboratory (NPL Certificate No. 120R11/921011/D18) and the National
Bureau of Standards within the limitations of the NPL’s and the NBS’s
calibration services, or have been derived from known values of physical
contacts.
