PR203 Radiometer
Irradian Limited
1
The Irradian portable phototherapy radiometer model PR203 is designed
specifically to measure directly the irradiance of blue light for the
treatment of hyperbilirubinaemia in new born babies.
The photodiode and colour glass filters are designed to give a spectral
response closely matching the bilirubin phototherapy action spectrum.
Good blocking of the detectors response outside the bandpass ensures
the radiometer does not measure non-therapeutic light. The cosine
corrected diffuser input ensures accurate measurements where ever the
light source.
The radiometer comprises of a hand held display unit with micro
processor control and a detector / amplifier assembly with connecting
cable and associated filters. The sensor in the detector assembly is a
silicon photodiode with excellent linearity and long term stability.
Note: The PR203 is NOT an ultra violet radiometer and should NOT be
use to measure the output of ultra violet lamps in UV phototherapy
treatment.
