Who it's for
- Best single-unit digital in Gun Safe Hygrometer – 4 Picks, Target Humidity and a Salt Test: For any gun safe owner who opens the safe often anyway and wants a readable digital gauge with high/low memory; you have to open the door to read it, which lets room air in.
What we like
- Touchscreen shows current plus high/low humidity and temperature
- Updates every 10 seconds, per the manual
- Door bracket or fold-out stand, so it needs no shelf space
What to know first
- Must open the safe to read it
- No humidity tolerance in the manual; one owner found it slightly off his other meters and another's sensor failed in a day
