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
