Mini Hygrometer Thermometer Digital Indoor Humidity Gauge Monitor with Temperature Meter Sensor Fahrenheit (℉)

Super sensitive and accurate. With home heating costs ridiculously high, its a great tool for monitoring the ambient temperature and adjusting accordingly. Thanks, Goabroa!!!

I shoved it in the slot for the Bb whistle and it works great- doesnt fall out and seems accurate.

I have 3 on these and got 3 different temperatures and three different humidity levels sitting side by side. They were +/- 3 degrees and 10% humidity

Great size, nice and small Only used it for a short time so am not sure about battery life yet

Small units are definitely function over form, which is fine for the price point. The construction design seems like its intended to be able to mount onto other objects. There is no branding so I suspect multiple companies sell them and/or add them to their preexisting products. They need a few hours to settle once theyve been removed from the packaging. Out of the 5 purchased they ran about 3 degrees in deviation from each other, both temperature & humidity. Recommend buying 4-6 units & placing them next to each other. Any that are way off the average reading should be returned as defective. The lack of instructions/manual & crude construction doesnt instill a ton of confidence so I use two in each of my cigar tupperdors. Ive been happy with the synchronization & ease of reading.

Threw it in a Ziploc gallon bag with a boveda 72% pack for a few hours and it read 70%. I call that good enough. Use it in my cigar humidor as a secondary instrument to the main hygrometer. For 6 bucks I say its worth it for a 2nd humidity check. Probably wouldnt trust it for a primary. Seems like a solid product.

A great little unit, helps in my dry climate to set my humidifier correctly. Even came with spare batteries

I am really pleased with this little device. I keep it in my guitar case (along with a humidifier) so I can monitor humidity. It is very small but easy to read and they include a second set of batteries. I plan on buy several more for each of my guitars.

so I bought this to prove it. Sure enough, my office is the hottest place in the building. Nobody cared, but at least now I know I wasnt just whining.

Nice item. Easy to read but still very small. Stick taped to my clock so it is easily checked. Indoor temperature is spot on accurate too
