A radiometer that incorporates multiple UV bandwidth sensors, defined in nanometers, and includes connectors for inserting a cable that is used to connect to another sensor, or to a data collection module (DCM) in a multidrop, or daisy-chain arrangement. Each sensor can be positioned at any point on a three-dimensional work piece, and will receive UV energy at the aperture having an optical component. The collected energy is directed to a detector in the sensor. A processor in the body of the sensor then computes the amount of UV radiation based on signals from the detector. This information is transferred to and stored in a data collection module to which the sensor string is connected. Data stored in the DCM can then be transferred to a computer for display purposes. The sensors and DCM can be tethered to the computer for real-time measurement readings when adjusting the UV lamps.
