Warning: Old furnace gauges vs. new digital readouts

I mean, we used to judge the melt by the color of the flame, which was kinda sketchy sometimes. Last Thursday, the digital monitor showed a weird spike before the old dial even twitched, so we cooled it down a bit. Ended up with a really clean pour on a tricky gear casting, no slag pockets at all. Idk, just a small thing, but it felt like a win after all those years of guessing.
