## Description

desertcart.com: 6 Pack Mini Hygrometer Indoor Humidity Meter, Small Digital Thermometer Humidity Gauge Meter, Indoor Thermometer Hygrometer Monitor Fahrenheit (℉) for Thermostat Reptile Tank, Mason Jars : Patio, Lawn & Garden

Review: Reliable little sensors for filament care - These mini hygrometers have become indispensable in my filament storage routine. I use them inside my dry boxes / storage bins to keep filament moisture-free, and they do the job well—no surprises or moisture-related prints going bad. The display is easy to read at a glance, showing both humidity and temperature clearly. Their small, versatile form factor means I can tuck one into any container or spool box without taking up space. Considering you get six units in a pack, it’s a great price for what you get. Bottom line: For the price and utility, this 6-pack is a smart buy for anyone serious about controlling moisture in their 3D printing materials.
Review: Small, Accurate, and More Honest Than People Who Say They Shoot Film - These little hygrometers work surprisingly well. They read humidity and temperature fast, the screens are clear, and you can stick them in a reptile tank, a mason jar, or a filament bin without any fuss. They are small enough that you will lose at least one within a week, but that is part of the charm. And like most people calling their digital videos films, these hygrometers pretend to be tiny weather stations when they are really just sensors. At least they admit it. No chemistry, no emulsion, no reels, no lab processing. Just data. Which means these hygrometers are already more honest about what they are than half the internet. Good little gadgets. Straight shooters. Not films.

### ⭐⭐⭐⭐ Good budget hygrometer!
*by J***G on January 5, 2026*

​If you need a cost-effective way to monitor multiple storage containers at once, these mini hygrometer thermometers are a great choice. I bought a pack of these to track the conditions inside my large mason jars for cat food and my vacuum-sealed 3D filament bags. ​Generally Reliable Performance ​While these aren't laboratory-grade instruments, they are generally okay for everyday use. You might notice that each unit gives a slightly different number when placed side-by-side, but they perform consistently enough to tell you if your storage is "safe" or "wet." For the price, they are much better value than the expensive single units. ​Best Uses: ​Cat Food Storage: Perfect for dropping into a large jar to ensure no moisture is getting in that could spoil the food. ​3D Filament: Essential for checking if your desiccant is still working. Even if the accuracy varies by a few percent, it’s easy to see when the humidity starts to climb. ​Compact Size: They fit easily into almost any container without taking up valuable space. ​Final Verdict ​They are priced better than most options on the market. If you don't mind a bit of variation in the numbers, these are an excellent, affordable tool for any "Maker" or pet owner looking to protect their supplies. ​A Quick Tip for your Review: ​Users often appreciate knowing that these typically bottom out at 10% humidity. If you see yours reading "10%" in your filament bags, that usually means it's actually even lower than that, which is great news for your plastic!
