I got these more for temperature than humidity, though I will likely use some around my 3d printer filament where humidity is the main issue.I put some in different places of the house to see what the temps are in different rooms. I put then all in 1 room initially and found each to differ by as much as 5 degrees. This is ok for most applications, but not ideal, seems they could be a little more accurate and consistent.

I ordered these for my reptiles, upon receiving them, total of 8 out of 12 actually worked. Four of them The LED screen didn't display anything.

I like these types of thermometer because they are compact, I use ones already around the house that doesn't have a probe, so when I saw these similar ones with a probe, I wanted to get this 12pk (12-Pack LCD Digital Hygrometer and Thermometer, Indoor Hygrometer Meter, Humidity Gauge for Reptile Enclosures, Greenhouses (SD3013-with Probe)) for other applications. I have placed them at my windows and put the probe up higher where the panes meet to monitor the draft temperatures.I put 5 of them in one window just to test it out with the probes in the same location, The humidity ranged from 38% to 42% and the temperature spanned from 45.8F to 55.7F degrees, it's pretty cold and drafty by the window since it's in the low 20s right now outside. I have also placed one inside of my sauna tent to monitor the humidity and temperature when I'm doing the steam sauna. That's been interesting to watch it fluctuate depending on where I put the probe. I have other thermometers inside the tent and this one seems to be within 5% and 5 degrees of the other ones. I'm not sure which one is accurate but as long as they are relatively close, it's fine by me. This 12pk is reasonably priced and I can monitor all kinds of conditions whether it's using in my microgreens area or near other plants or in the bedroom near the humidifier, etc. It's interesting stats to look at and I'm glad I was able to get these to try out.

This order came with 12 thermometers that show humidity as well as temperature. These are not scientific instruments by any stretch but for daily use to get directionally correct temp and humidity readings they work great. I’m using them to get a better understanding of how heat is dispersed in my house to identify hot or cold spots. For that purpose it works well. Each device comes with batteries installed. To get the, operational, user opens the battery cover, removes the batteries and then removes the film under the batteries. You cannot just pull the film out it hour opening the cover or you might break the cover or lose the batteries as they fly out. I did get a couple of devices that were not accurate. See the pictures. One shows 158 degrees which can’t be reset. For some, I simply pulled the batteries which reset the device. It did not work with this one. But having 12 means it didn’t matter much. The other picture shows the devices were showing nearly the same reading in the same location so the accuracy seems ok between devices. Overall they are smaller than I thought but seem to be working well.

I use these to store 3D printing filament and they work great. The most commonly used plastic for 3D printing is hygroscopic (it draws in water from the air) so it's important to store it with desiccant to keep it dry. I keep in in air-tight storage containers, then close one of these hygrometers in the tote with it. I try to keep the filament below 30% RH at all times, and these little digital hygrometers are perfect for knowing exactly what the RH is inside of the storage tote and if the desiccant needs to be replaced.I am just leaving the coiled up wire at the bottom of the storage tote, and I have the display mounted inside the clear plastic lid so you can read it just by looking at the top of the tote. These work perfectly because they are so small and light. I just used small strips of 3M VHB around the edge and stuck it right to the inside of the clear lid.If you need a small hygrometer, these will work great and are a very good deal for the 12!

The "12-Pack LCD Digital Hygrometer and Thermometer, Indoor Hygrometer Meter, Humidity Gauge (SD3013-with Probe)" I received are a bit off measuring humidity.These work, but they aren't very accurate measuring humidity. I noticed about a 7% difference between these and my trusted Hygrometer. Temperature reading however is within listed spects with the ones I received.As other reviews mention, I needed to take the batteries out in order to remove the protective plastic. No, don't try to just pull the clear plastic tab or you will most likely damage the unit.I like that these have a corded probe so I can place the probe into tight spots where it may be otherwise difficult to have an all-in-one display.Im case you may be wondering... Of course the probe isn't waterproof- it's a hygrometer. Submerging it would short out the probe. It needs humidity to pass over the sensor. The sensor is exposed to the air inside the probe casing.If you need just a submersible probe for temperature readings, search elsewhere on Amazon. This is for reptile enclosures, 3d filament chambers/enclosed 3D printers, mycology tubs, etc.Would I recommend these? Probably not due to the inaccurate Hygrometer readings throughout all the ones I tested hoping to find one that more closely matched a trusted meter. However, if you need a bunch of these, and you are on a budget, AND you can test them so you know how far off yours are, then it may be a viable option.
