Query: does what it's supposed

thing displays temperature accurately, though I made the mistake of putting on the grill when I was scorching the grates, and it left a brown burn mark on the lens. I haven't tried scrubbing out the burn mark since it's still transparent and I can see through it, that, and I'm feeling a bit lazy lately. but other than that, things works fine
