2.1 Operation
The Loctite
®
UV Spot Radiometer is well suited for most production
operations. The UV Spot Radiometer can be used to verify that the output
from the wand system, under test, is proper for the curing process. When
making measurements the wand should be held as straight as possible,
and the ends should be clean.
