Mini Hygrometer Thermometer 2PCS Mini Digital Humidity Gauge, AikTryee Hygrometer Indoor Humidity Monitor, Temperature Humidity Gauge Meter for Humidors, Greenhouse, Garden, Cellar, Closet, Etc

I got this to go in my guitar case. I had alternately been over-humidifying and under-humidifying, neither of which was ideal. Where to mount it so that it wouldnt rattle around? I decided to wedge a piece of plastic from a notebook cover into the area near the storage box of the case. Then I used Velcro to attach the humidifier to the plastic, so that I could get if off to change the batteries. Good luck.

Much more accurate than the analog hygrometers that came with my humidors. Its nice to have two of them. I put them both in the same humidor, and they read the exact same. Then I moved them to different places in the same humidor, and they registered the difference in humidity in different spots. I then swapped places with them, and they each adjusted to the same readout the other had in the same spot. Very pleased.

Works amazing. Helped a TON with not having to guess the % my humidity was at.

I have had these for a couple of years. They come with batteries installed. Best to reboot them before use. Take both batteries out, make sure the screen goes totally blank, reinstall batteries. If you reinstall batteries before screen goes totally blank it will not reboot, it will go back to what it was before batteries were removed. If you have problem with them down the road, do a reboot.

These are tiny yet I’m still able to read them. I love them. I use them in my leopard geckos tank. I haven’t used the adhesive to put it up on the tank. I just stuck them inside on my hot and cool side. Works awesome. Same temps as what my heat gun is saying. Love that there was extra batteries in the package too!!

I use several of these to monitor humidity inside musical instrument cases. I occasionally check their calibration using hydrated potassium carbonate as a standard, and I have never found one more than one percent high or low. Allowing for the value of the four spare batteries if you bought them at a drugstore, the devices themselves are almost free!

Works well in humidor and wine fridge

Does what it says on the tin. Simple, easy to read, and reasonably accurate.

I purchased these gauges to keep a watch on the humidity in my guitar cases.

I got these for the inside of my bearded dragons tank, and they adhere to the tank, easily or easily to read seem to be accurate
