The Dosimeter-Radiometer measures the UV Dose (energy) and UV Irradiance inside the UV Curing Equipment and is a Self contained one channel device. The Dosimeter- Radiometer is traceable to the National Institute of Standards (NIST). Units of measurement for the UV Dose (energy) are Joules per square centimeter (J/cm2) and units for UV Irradiance are Watts per square centimeter (W/cm2).
