Mini Thermometer Hygrometer Digital Indoor

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.

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.

I fitted the hydros to some Filament containers and they all work well.

These are great Hygrometers and good value for money. Using these to monitor humidity of my 3d printer filament. Have had some for about 1year now and the batteries that come with them seem to last a long time as i have not had to change any. They are small and compact but the display is easily readable from a distance Easy to use, they are already on when they arrive so nothing to setup. They seem to be consistent across all the ones i have purchased.

After reading reviews I calibrated the 6 units I bought alongside 4 other higher quality devices I already owned. After 3 days of regular monitoring I found the following: Humidity - all units within 1% of each other and within 1 - 2% of calibrating devices Temperature - all units within 0.2 degrees C of each other and between 0.7 and 1.0 degrees of calibrating devices ( slightly higher ) Given the price and size I would highly recommend because the variations in humidity and temperature are small (in particular humidity) ** update ** the test was in humidity of circa 50%, upon use in the 60% range I found the units to be out by around 5% but the good thing was, it was consistent across all the units so I was able to use ok because calibrated alongside trusted kit. I guess the answer is they aren’t super accurate but can be used reasonably reliably if you can calibrate.

Full marks for the photography! These are 45mm. They have lugs on the side that look like they are made to push fit into a panel. They also have a flange to cover poor cut out. With 3 of them next to each other, they all read the same temperature and very similar humidity. The viewable area is barely 24mm. I found them difficult to read. They are cheap enough but I wish I spent a bit more for something a little better.

They arrived quickly, but the battery in one of them was totally flat. I will have to put new batteries in, which is not good and hopefully it will work. The ones that are working seem to be accurate.

Very good.

Tun was sie sollen. Messen sogar ab 10% Feuchtigkeit. In der Beschreibung heißt es, sie würden erst ab 20% messen. Perfekt also für meine Filamentboxen. Die Verpackung könnte liebevoller gestaltet sein. Die Geräte werden einfach lose in einem Luftpolsterumschlag verschickt.

Veramente molto utile. Lo sto usando per verificare l'umiditá delle bobine di filamento per la stampante 3D. Quindi se stai cercando un Igrometro per quella stampa per l'umiditá dell'AMS di BambuLab, questo é perfetto. Con un po' di forza entra e non uscirá mai piú. Consigliato

C’est génial petit pratique

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

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.
