Self-adhesive indicator to check the UV irradiation level
NiGK conducted a sensitivity test to evaluate the sensitivity of the UV LABEL™ to a UV-C light. In this experiment, UV-C light has an output of 1 watt and a wavelength of 253.7nm and duration of the irradiation was 10 minutes per single cycle. After exposure to the light, the UV-S (most sensitive type among all types) responded sharply to single cycle. The UV-H could be visually identified by 5th cycle. UV LABEL™ are not an indicator of disinfection, but they do give a good indication that the light is well working.
Note: Do not look directly at a UV light source. It may cause cataracts.
UV LABEL™ is single-use indicators irreversibly changes its color from white to various color by ultraviolet light irradiation. 4 types of products are available depends on the sensitivity required.
-Use determining the hardness of UV-curable resins (inks, paints, adhesives, etc.)
-Maintenance (determining the time for replacement) of UV lamps (metal-halide, mercury-vapor, germicidal lamps)
-Checking sunlight UV levels
-Checking gamma-ray or electron beam irradiation (UV-S, UV-H)
