Abstract: An ultraviolet (UV) radiometer includes as one component a data collection unit which is sufficiently small that it can be placed in UV curing applications which have normally been inaccessible as another component a data reader into which the data collection unit is inserted for displaying and/or processing the actual data collected by the data collection unit during a process run. Because of its small size, the data collection unit makes it possible to obtain true process control in applications that could not previously be monitored. After making a dosage measurement, the data collection unit is inserted into the data reader to display the actual data collected during a UV curing run. After reading the data in the data collection unit, the data reader clears the previously stored data and resets the unit to take a new dosage reading.
