Room Thermometer

Execellent quality Hygrometer using to check humidity of 3d printer filiment. Like that you can turn it off so saving battery life when not in use. and easy to use. Functionality is good not only humidity but a temperature moniter as well Not sure of the battery life as only just received them and they were all active on arrival They look good in the cereal box with the fillament making it easy to desplay and read.

So these are decent enough, I use them for my 3d printing filament boxes so I can review the ambient air in each storage box. There is a range of up to 7 degrees between the highest and lowest readings in temperature, humidity less so, which is what I care about. They all work out of the box no issues. One nitpicky thing is, the viewing angle is quite bad and so you cant easily read the data if you place it somewhere at a weird angle. All in all: Recommended

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.

Great quality, great price!

i bought these to put inside 3d filament storage boxes, so that i could measure the moisture in the box. They work perfectly, and clearly display the humidity and temperature in easy to read black text on the screen, they are incredibly easy to use with no setup needed at all. I will be buying more for sure

I bought this pack of 6 room thermometers and use them in pairs to get an average reading. Tested all together they read +/-1°C of each other, with similar variance on the humidity reading. However, for the price, this is totally acceptable. Plus they're discrete left in a room, and clearly show the readings that I want to see.

Delivery was really quick and although the products seemed accurate at first, I found that the RH reading, when below 20% it would keep jumping between 10 and 20%, and you can’t say which value it truly is..

Great value for money

Perfetto al mio utilizzo . Ora posso tener sotto controllo l'umidità nell'essicatore delle bobine di stampa, e anche l'umidità presente in mansarda .

Precisos, baratos y muy fáciles de incorporar a tus diseños.

Bardzo dobrze spisują się jako mierniki wilgotności w pojemnikach na filamenty drukarki 3D. Bateria wystarcza na bardzo długo.

Les thermomètres fonctionnent bien dans leurs tolérance.

It's cheaply built, and non calibrated. All three have different temperatures and humidity percentages ranging by 5 points for all three for humid and temp. They all were on in the packages with the pull tabs for batteries removed. If you want cheaply built items for a moderate cost. This is it.
