When There's No Cure

It must be emphasized that the proper and repeatable placement of the probe is critical to using handheld measurement of UV energy. Naughton suggests "a trap door or opening of some sort into the cure area so the probe can be inserted into the optical path in such a way as to have the sensor right at the point of curing." To be able to meaningfully compare repeated measurements over time, the probe must be placed in the same location each time. "The converter who is diligent about taking measurements in a standard fashion will be able to establish benchmarks that can be used as a quality tool in their operations," emphasizes Bade.
