UV203-3 Radiometer Irradian Limited
1
The Irradian portable radiometer model UV203-3 is specially designed for
the measurement of underwater irradiance in the UVA band, the UVB2
band and the radiometric band between 400 and 700nm.
The equipment comprises of a display unit and a submersible detector
head with three photodiode detectors, linked with a robust 10 metre
cable.
The micro-processor controlled display unit features a 4½ digit direct
reading liquid crystal display, auto or manual gain control of the detector
amplifiers and detector selection. Operations include back ground zero
measurement and display hold. The radiometer can also be used to
measure the average irradiance on a selected detector and record the
minimum and maximum values during the averaging period. In addition
the integrated irradiance in mJ/m² or J/m² is calculated.
The detector head comprises of three, high stability photodiode detectors
with glass absorption filters for the selected spectral band and a cosine
corrected input diffuser. Each of the detectors has its own high gain, low
noise amplifier and digitiser. This design ensures only resilient digital
signals are transmitted along the interconnecting cable.
The model UV203-3 provides the following:
1 UV203-3 display unit with two PP9 type batteries
1 DET203-3UV-VIS triple detector with 10 metre cable
1 RS232 interface cable
1 Blanking plate
1 Handbook
1 Calibration certificate
1 CC-8 Foam lined carrying case.
