There are several radiometer models on the market that provide various types of information. A radiometer should be chosen to fit the application and the information required.
Functions range from simple intensity and simple dosage to sophisticated mapping devices.
Which wavelength to measure is also a matter of choice. This is because the majority of the chemistry responds to this band of energy. If it is desirable to measure other parts of the UV spectrum, a radiometer is available to do so. Certain chemistry is formulated to respond to different wavelengths of light and for different applications. Radiometers are also configured for use in different applications.
