When There's No Cure

Handheld radiometers can be used to measure the actual intensity of UV-A, UV-B, UV-C, and UV-V. As mentioned earlier, they typically require a separate probe attachment for each of these bandwidths. Midlik points out the advantage of these portable units: "A mobile measurement unit can be easily moved between multiple UV irradiators. Most converters choose a mobile unit since it allows them the flexibility to monitor numerous UV systems without having to invest in a measurement unit for each."
