Testing a UV/UVC test card
Added 2023-02-09 00:28:13 +0000 UTCJust a quick video to show the two modes of this card in operation.
It's designed to give a visual indication that your UV source is emitting roughly in the right spectrum. The test method for both types of UV is different.
The card can also be used to test things like glasses for their ability to block UVC. Quite handy when experimenting with germicidal lamps.

2023-02-09 02:50:22 +0000 UTCYou have one already -- the remote control that turns on and off the set will do it... when you think the set is distributing poo you press the power button... if it shuts off then you know it was! :)
