Mini Hygrometer, Mini thermometer

I like to be aware of the temperature and humidity, tracking it for my skin care routine, and what to wear, and these mini thermometers work perfectly. They are accurate and since they come as a 4 pack you can put them in more than one place. It's a great value for the price and it even came with a spare battery for each, but I haven't had to change one yet. They are small enough to be placed unobtrusively, yet the numbers are large enough to easily read - great combo, highly recommend.

I put one of these in my refrigerator freezer and upright freezer at home. At work we use them to monitor the temperature in pump rooms that need to be kept above freezing in the winter. We also put them in our walk-in freezers and coolers for instant feedback on the temperature.

I bought these little gadgets to monitor the humidity and temperature in my house, and I must say they are quite handy and accurate. They are small, easy to read, and easy to install. They come with batteries and adhesive stickers, so you can stick them anywhere you want. I have one in my bedroom, one in my living room, one in my bathroom, and one in my fridge. Thermometers are very useful for keeping track of the weather and adjusting the thermostat accordingly. They also help me avoid getting sick or sweaty by telling me if the air is too dry or too humid. Hygrometers are also useful for keeping track of the moisture levels in my plants, food, and skin. They also help me avoid getting moldy or wrinkly by telling me if the air is too wet or too dry. These gadgets are great for anyone who cares about their comfort and health. They are also fun to play with and compare with each other. Sometimes I like to move them around and see how the readings change. Sometimes I like to prank my family and friends by changing the settings or placing them in weird places. They always get a laugh out of it. These gadgets are worth every penny. They are cheap, reliable, and entertaining. They are one of the best purchases I have ever made on Amazon. I would highly recommend them to anyone who needs a mini digital thermometer hygrometer indoor humidity temperature meter gauge. Or four.

Very pleased with this purchase. Thermometer is accurate +/- 1° F and hygrometer is consistent among the 4 received. Immediately after unboxing, one had wildy different measurements and I was afraid it was going to be a dud. I put them in the bathroom during a shower and immediately after the shower all 4 were exactly the same- though one changed just before I took the picture as the room temp and humidity began to drop. They each adjust at slightly different speeds, but stabilize within a couple minutes. I compared the temperature readings to those on 2 different digital oven thermometers and my old thermometer/hygrometer (on which the humidity always measures 99%, so cannot compare hygrometers). As long as the temperature was stable, they were all within 2° of each other. My oven thermometers actually measured 1.5° apart. So I'm pretty confident in the performance of these. I purchased these to monitor the environment in my succulent seeding domes, based on the reviews of high accuracy and cost. Monitors with corded probes would have been more convenient, but I couldn't find them at a similar price with good accuracy reviews and without the humidity reading being larger font than temperature. The temp and humidity fonts are the same on these. The humidity reading is first (left), which threw me off initially since I'm mostly interested in temperature, and the temp and humidity readings are very similar in my setting (usually 75-80 for both). I resolved that by putting a small mark underneath the temperature with a silver sharpie, which draws my eye to it. The back portion of these happen to be the exact height as an Avery 5961 address label (1") which I had handy. I cut a label at the measured width and stuck the label onto the plastic humidity dome, cut out the portion with the label, and pressed the back of the monitor into the cutout. I have noticed that the dome-mounted temperature is occasionally a couple degrees below the one that sits inside freely atop the seed trays (there temporarily), but at other times it's spot on. I chalk that up to location and being closer to outside the dome (ambient temp about 15 deg below dome temp). I just set this all up last night. But it's not a big deal if it is a persistent finding.

I keep isopods and 2 disabled hamsters. These are very accurate and sensitive, which is just what I needed to keep an eye on temp and humidity. It came with extra batteries and sticky backs. I dont plan to use the stickies and am making a holder for them to make them easily removeable so I can get to the back where the battery is located. The sticky backs seem that they would block battery acesses. The one thats 1% off just changed as I took the picture. I prefer these as both the humidity and temperature are equal in size and make it a lot easier to read. They are small and compact, perfect to not take a lot of wall space in your enclosure. They are quick to adjust. I left them for a day to even out since its very cold where I live. They need time to balance after shipment, thats just how any hygrometer/temperature gage works. Overall I do plan to get more when I need to.

For the price, these are well made and work extremely well. They are accurate when measuring the temperature as well as the humidity levels. The are about 2 inches in length and they come with multiple sets of batteries which can keep these going for years. I haven't even changed the batteries out yet on any of these and I have had these for well over a year now. I would definitely buy these again if I needed some more but these look like they're brand new still so I don't see that happening anytime soon.

I was able to get all 4 of these working, but one would lock up under cold conditions (that is, about 52 degrees F), then be unusable until the battery was removed and replaced. Another had the thin door iffy on pressing the batteries in, so sometimes went off on its own. Don't expect precision in the temperature reading - side by side units had a variance of about 2 degrees in our case. Good enough, but don't use them for science experiments or anything.

I purchased sets of 4 twice (June and December 2021.) They are used in my 3D Printer Filament individual storage containers to measure the humidity inside the plastic storage cases. The units are all within 1 degree F and 1% of humidity of each other (even before putting them in the cases), so there is no problems with consistency between units. I went with this "brand/seller" since they showed in the description to have better accuracy specs than similar units elsewhere on Amazon (can't say if that is really true or not.) The set contained 4 extra batteries, which was good since the batteries (takes 2 for each) were DEAD in one of the units in my second purchase. Hence I used half of my extra batteries just the get the product working as it should have worked out of the box. I messaged the seller about the disappointment that one of the units had 2 dead batteries, but unlike every other seller I ever sent a message to, this seller NEVER RESPONDED TO MY MESSAGE! That was REALLY disappointing and between the lack of a response and the fact that one of the units did not properly work as shipped led me to remove a star from the rating. This would easily be a definite buy if the seller had responded, even though I had to use half of my extra batteries to make the product work as expected. All in all, if the units go back on sale I may purchase a 3rd set. But that lack of seller response still irks me.

Ils semblent après quelque tests comparatifs fonctionner adéquatement tous les 4. Degrés F° Possibilité de les incruster avec des clips dans le côté

pretty accurate
