certification. UV protective glasses should be available with the system

being tested. If they are not available, they may be purchased from

Loctite. Safety Glasses Item # 97210.

2. Potentially exposed skin should be covered. Long sleeves and

protective gloves should be worn when measuring UV Wand intensity.

3. Never look directly at the output from the UV Wand.

4. Make Sure that the Radiometer reading is Zero, before removing the

UV Wand from the Sensor Head.

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.
