Sensor Calibration
The SU-200 has a standard UV calibration factor of exactly:
Multiply this calibration factor by the measured mV signal to convert sensor output to UV-A in units of W m

Example of UV-A measurement with an Apogee UV-A sensor.
Full sunlight yields UV-A radiation on a horizontal plane at the
Earth's surface of approximately 60 W m
output signal of 6 mV. The signal is converted to UV-A
radiation by multiplying by the calibration factor of 10 W m
per mV.
