Calibration Traceability
Apogee SU-100 UV sensors are calibrated through side-by-side comparison to the mean of three Apogee model
SU-100 transfer standard UV sensors under high intensity discharge metal halide lamps. The transfer standard UV
sensors are calibrated through side-by-side comparison to an Apogee model PS-200 spectroradiometer under
sunlight (clear sky conditions) in Logan, Utah. The PS-200 is calibrated with a LI-COR model 1800-02 Optical
Radiation Calibrator using a 200 W quartz halogen lamp. The 1800-02 and quartz halogen lamp are traceable to
the National Institute of Standards and Technology (NIST).

Spectral response estimate of Apogee
SU-100 UV sensors. Spectral response
measurements were made at 10 nm
increments across a wavelength range
of 200 to 450 nm in a monochromator
with an attached electric light source.
Measured spectral data were
normalized at 350 nm.
