Humidity Meter Indoor Thermometer 6-Pack Mini Digital Thermometer Hygrometer Indoor Temperature Humidity Meters Gauge LCD Display Fahrenheit (℉) for Greenhouse, Reptile Tank, Cellar, Closet

This Humidity Meter Indoor Thermometer is excellent! It provides accurate readings for both temperature and humidity, helping me keep track of indoor conditions easily. The display is clear and easy to read at a glance, and the compact design fits anywhere in the home. It feels well-built and reliable, and the measurements update quickly, giving real-time information to help maintain a comfortable environment. I’ve been able to use it to monitor humidity for plants and overall home comfort, which has been very helpful. If you want a simple, accurate, and reliable way to monitor indoor temperature and humidity, this device is a great choice. Highly recommend!

Accuracy and precision at a great price what can I say. Out of the 6 units one or two of them seemed to have a slight deviation in the temperature about 1-2 degrees higher but that is okay. I love that this came with six. I can keep one in each room and have a better idea of the climate in my house. I had a silver fish infestation in my bathroom due to high humidity but during the winter months my nose becomes liable to bleed like a (insert funny simile) due to LOW humidity so these little guys help me keep my nose from bleeding and my house silverfish free! Seems like these would also be great to throw in a humidor for cigars. Or if you buy a large quantity of the green sticky stuff and you want to make sure it stays fresh!

I got these to put on my plant stands to measure the amount of humidity since I have to run humidifiers for my plants. I just wanted to make sure that I'm keeping my living room at the level I need for my plants. My second use was for my mushroom (legal ones!) tank, since mushrooms need a specific level of humidity for different stages of growth. They work great for the plant stands. I didn't need anything fancy, and the size is perfect so they don't stick out. They are accurate as far as I can tell. For the mushroom tank, not so much. It was reading the level fine, but even after I know the humidity decreased it would stay at 99%. I even took it out of the tank and put it next to one of my plant stand monitors. It still stayed at 99% for a half hour or so. I put it back in the tank, and the monitor slowly started to go back up. Then, I repeated the above. My best guess is that these can't handle staying in a high humidity environment, and I think it needs time to "dry out" before it will be accurate again. I will be searching for another for my tank. Besides the tank issue, these are good for the price.

The hygrometer set is an excellent value. The displays are clear and easy to read, showing both temperature and humidity at a glance. I placed them in different rooms (bedroom, living room, nursery, and basement), and the readings are consistent and accurate when compared side by side.very easy to use and small enough that you can even use it in jars for curing.

The order arrived quickly and was packaged very well. All of the units were in good condition and working right out of the box, which was great to see. Setup was simple, and everything functioned exactly as expected. The only downside is that the batteries come pre-installed and the units appear to be turned on during storage and shipping. Because of that, the batteries have likely been draining since the product was manufactured. While everything worked when I received it, it does make me wonder how long the batteries will last after purchase. Overall, it’s a good product and I’m happy with the purchase. If the manufacturer shipped the units with a battery isolation tab or with the batteries not actively powering the device, it would make the product even better.

Very accurate and reliable humidity readings at surprisingly inexpensive price. Use in cigar humidors to protect investments, in home locations to monitor moisture levels, and in any application where accurate measure of humidity is desired.

I've ordered two of these (so 12 total units). My latest shipment came with 1 out of the 6 dead on arrival. All of these are packaged with the batteries CONNECTED. Your battery life will last as short as it was sitting on the shelf doing nothing. My DOA unit came with dead batteries. It also looked like they were leaking/corroded. Anything under 10%RH is golden for keeping my 3D printer filament dry. Just know it's not designed to be super accurate or read anything below 10%RH. I docked 2 stars because they come with the batteries already connected, and one of mine was DOA.

What else can I say! Bought this listing because it comes with 6 and after searching amazon and comparing, this is the best deal! Performance test: For sake of comparison, and to see if there are calibration variances, I put two of these hygrometers in my humidor with 72% bovida packs, 1 week later, both read 72%! Very happy, can’t ask for more! These are leaps and bounds better and more accurate than my old analog spring guage that seemed to be just a shot in the dark. When moving around, (out of the humidor), these change readings almost immediately so it’s actively reading and updating the humidity in real time. I’m hoping battery life is just as good!
