The Zoo Med UVI Radiometer measures UVB and provides readings based on the UV Index which is the system developed by the World Health Organisation to grade the levels of radiation from the sun’s rays.
A quick reference scale on the meter helps determine correct UVI level for various species based on the Ferguson Zone system that takes into account range, activity and behaviour of the animal. The UVI meters response curve is weighted to match the Vitamin D action spectrum. Can also be used to determine if lamps are producing safe and effective levels of UVB and to compare brands.
