6 Pack Mini Digital Thermometer Hygrometer,Indoor Temperature and Humidity Gauge Meter Monitor Fahrenheit (℉) for Home,Greenhouse,Jars

Great deal for SIX hygrometers. They are fairly accurate. A must have for those who want to keep tabs on humidity levels for health and maintenance of musical instruments, etc. I have one next to my cello and in the bedroom to make sure that I keep an eye on the humidity level where it matters.

Bottom line. It works. Presents accurate temperature and humidity readings. Is quite small and allows for placement in various locations in your home without shouting its existence. I’ve placed them in a cabinet where I have all my prescription meds and vitamins. Critical it not get too warm or humid in that type of area. Recommend without reservations. And the battery lasts a long time.

Not completely accurate (see photo of them all together with different measurements) - so I would not recommend in areas where accuracy is importance such as animal or delicate plant habitats etc. However, they are close enough to get the gist of the information for indoor and outdoor spaces, and for that I give 4 stars

Works well no complaints!

These hygrometers are a great deal for the price. Check out the photo—the one on the right has desiccant beads in it and it’s reading a lower humidity percentage, while the one on the left (no beads) is showing a higher reading. They’ve been sitting next to each other in the same spot for about two weeks now, and the difference stays steady. That makes total sense: the desiccant is pulling moisture out of the air inside its little chamber, so it reads drier, and the one without is just showing the real room humidity. Honestly, the fact that they’re both holding stable and behaving exactly how you’d expect gives me a lot of confidence they’re accurate. Super happy with these for the money.

Items work as expected. However, they shipped without battery cut-off shields (small plastic strips which keep new batteries from discharging until first use). As such, I have no way to know how far the life has been reduced.

Excellent tool for quality control and moisture mitigation.

These little Hygrometers are great. I used them in my Grove bags while curing. They are the perfect size to go into your curing bags or a mason jar. Highly recommend.

Good for jumping spider enclosures or other small invertebrates. Not perfectly accurate but gives a good enough estimate.

Works great love it

Il y a 1 ou 2 degré de différence entre quelques un. Donc pas parfaitement calibré, mais sinon c'est correct, la différence est pas énorme et est correcte pour mon utilisation.

These are obviously not highly scientific devices, but they are accurate enough for my intended uses. Each one is a little bit "off" from the next, even when placed together in the same space for an extended period. But none were very far off the mark and readings between each device showed only about +/- 1%. Close enough for the price!!

Feel very cheap and none of them display the same numbers but if you wanna get rough approximation, works probably fine ?!
