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

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 have these scattered throughout the house now and am very pleased. They are very consistent. 1 reads a percent high and another a percent low, but the other 4 all match. For the price I am very very pleased with the readings.

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.

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!

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.

These only measure down to 10% RH. That said anything more sensitive is going to be relatively expensive. Take two LR44 batteries and last about a year before replacing. Display is fine for a humidor, museum case, or filament storage bin.

Installed these units in our filament driers to monitor humidity of my 3D printer units. Only issue i see is the batteries all cam pre-installed with no plastic pieces to prevent the circuit from drawing power, so who knows how much battery is left or how long they sat on the shelf before shipping. Otherwise the unit functions as desired, is easy to read and seems accurate. We'll see how durable they are over time. Size was spot on what was advertised.

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.
