Does a scratched appearance on the yellow label affect the indicator functionality?

Asked by: bcng
Thank you for your inquiry bcng. As long as the scratch is just on the yellow outer cover and not on the center sensing element, the label should function properly.

Does the color will change with direct UV exposure (such as direct sun light) even if the temperature didn't exceed the allowed range?

Asked by: OZ1234
Thank you for your inquiry. When exposed to sunlight/UV Rays, there could be some slight yellowing of the melt chemical but the temperature events will not change to black unless the rated temperature is exceeded.
