Hygrometer Thermometer Digital Monitor

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.

Purchased these too check the humidity of my 3D printer/AMS and the box I use to keep my filament dry. Noticed that the humidity was high until I sorted that issue with dessicant beads, and then looked at the reading again. From 60% all the way down to 10%! These work really well and I will continue to use them to monitor the humidity. Brilliant product, might have to get more for more dry boxes.

Nice units fit well on tray in 3d printer filament container

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..

They seem to do the job. I have nothing to compare them to though. They were recommended to me by someone else,

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

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.
