Thlevel 3 Pack Hygrometer Thermometer Digital Monitor Humidity Meter Gauge for Humidifiers Dehumidifiers Greenhouse Basement Babyroom

After my latest adventure in 3D printing, I stumbled upon the Thlevel 3-Pack Hygrometer Thermometer, and let me just say—these little gadgets have changed my printing game more than my printer ever did!First off, I used these monitors in my Bambu P1S AMS unit, and after printing a 3D model to hold them they fit snugly like they were born for the job. Now I can keep an eye on the humidity while I’m printing, which means no more warping or failed prints due to the great humidity mystery. You know, that thing where you think, “Is it me, or is my filament just dramatically melting into a puddle of despair?”These hygrometers are easy to read—big, bold numbers that scream “LOOK AT ME!” even from across the room. Plus, they come in a three-pack, which means I can have one in the printer, one in the basement, and one in my sons room (for all those moments I wonder if my son is creating a tropical rainforest in there).The best part? They help me monitor the humidity levels in my house, and boy, does it keep me on my toes! If it gets too humid, I can adjust my dehumidifier faster than you can say “failed print.” It’s like having a mini weather station that only cares about my filament’s wellbeing.In summary, if you’re into 3D printing or just want to keep your house from feeling like a sauna, grab these hygrometers. They’re reliable, easy to use, and a must-have for anyone who believes that accurate humidity levels are the secret to life—right up there with pizza and coffee.

Good value for money and handy size for putting in areas where you don't want a hydrometer to stand out. Display is pretty clear, yet the build quality isn't the best and the devices aren't of the highest accuracy.

Only day 1, but they appear to work well. Just a minor discrepancy between their readings, which does fluctuate a bit. Overall, I think they'll do just fine.

We live in an old 1900's terraced house, and have damp issues. I have used the hygrometers to give me a clear indiviation of the humidity in the room, I then know to whack the dehumidifer on and get rid of that excess water. They are so simple to use and have a large display screen to the humidity is clearly visible. The brightness of the screen could be better but as a simple quick glance it works a treat

The work ok but if you leave them in the same place all of them will show different values of humidity and temperature. After 8h they will finally match but it takes forever. I use them to measure moisture for filaments so I have 2 in a box just to double check.

Just got into 3D printing an wanted to be able to check the temperature and humidity in the AMS, the body of the printer and the room itself. These were cheap for 3 units so decided to try. As you can see from the photo, when the units are in the same place, 1 out of the 3 gives a slightly different value to the other 2. It is only a small amount but I would have hoped they would have been a bit more consistent. I will use but if you need accuracy then you may want to bear this in mind.

Perfect for dealing with damp in my house and for keeping my terrarium at the right temp and humidity level!

Excellent!
