broke my Galileo thermometer, but (naturally) saved the beads. Ran through all the options, but this is infra-red. Clockwise from top left, they are blue, yellow, green and red.
Oh nice! I came across one of these thermometers in what used to be my son’s wardrobe. He moved out at least 10 years ago and we’ve only just found it 😊
@30pics4jackiesdiamond it was an interrupted fall, so the glass didn't shatter - moved rug into garage as it smelled of antifreeze. I was interested in what the IR did - ought to read up on it.
