A radiometer is generally used to monitor the output of a UVGI system. It measures the UV intensity produce by UV lamps. The Fixed Radiometer is a type of radiometer designed to indicate relative UV output. It is calibrated (i.e. set) to “100%” when the lamps are new and operating under normal air conditioning system operation. As the life of the lamps progresses, or if an unusual event such as a burned-out lamp occurs, the relative UV output will show significantly lower.
