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.

Working straight away, seem to be very accurate in reading temperature and humidity.

Use several of them inside 3D printer filament storage bags and they are easy to read with display clarity and precise readings. It's a small price to pay for monitoring humidity and keeping expensive filament in good condition. Would recommend.

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.

Great little Hygrometer/Thermometer. Gives percentage humidity and temperature in Celsius. Handy for accurate, at a glance, measurement of these environmental factors.

I bought three of these and all three have had issues since day one, but now that they've been in use for a few weeks they're all starting to die. I've bought some new LR44 batteries but this does not bring them back to life; I think the quality of the circuit is so poor that they just don't last long (4 weeks of use for me).Because of Amazon's awful policies, I can't even return them as faulty, they're just plain BAD.
