Slippery slope indeed

[Señor Maduro]

I have that same Temp/Humidity unit. I wish I could find another at Wal-mart, but it seems they don't have them anymore. Looks great and reads very well.

Good luck with the wife.

Home Depot carries a similar one by the same maker, it's in their indoor lawn and garden section. I picked one up last week.

Looks like a nice Hygrometer. Are you able to calibrate it?

The walmart Hygro's I've seen can't be calibrated. Of course I didn't really look too hard either.

Neither can be calibrated, I just did the salt test and then add or subtract by how much they're off. My Walmart one reads -1 and my Home Depot one reads -3

For $8 I can live with it being off a little bit. I'll just add a lttle piece of tape to remind me how much it's off.

That's what I did. I sharpied them with +1 and +3 to what I see.
