JEDEW 2 Pack Hygrometer Thermometer Digital Humidity Meter Indoor/Outdoor Humidity Monitor Reptile Thermo-Hygrometer for Greenhouse Humidors Terrarium Jars, Fahrenheit (℉) /Celsius(℃) (2)

I originally bought these to monitor the humidity in my Bambu AMS units and in my airtight filament storage tubs with desiccant, and they've been fantastic. They're small enough to fit almost anywhere, yet the display is large and easy to read at a glance.The humidity readings have been consistent and make it easy to know when it's time to recharge or replace the desiccant, which helps keep my filament in great condition. They've become an essential part of my 3D printing setup.One unexpected bonus was that each unit came with a spare battery. That was a nice surprise and shows the manufacturer put some thought into the customer experience.If you're into 3D printing or just need a reliable way to monitor temperature and humidity in small spaces, I can definitely recommend these. Great value for the price!

I picked up this 2-pack hygrometer/thermometer to keep an eye on humidity levels in a couple different places, and they’ve been working great so far. They’re small, lightweight, and easy to place just about anywhere, which makes them really convenient for jars, storage bins, or small spaces.The display is clear and easy to read, showing both temperature and humidity at a glance. I like that you can switch between Fahrenheit and Celsius depending on your preference. The readings seem accurate as well—I compared them with another humidity monitor I already had and they were very close.I’m currently using one in a storage container and the other in a small indoor setup, and both have been consistent with their readings. For something this compact, they do exactly what they’re supposed to without any complicated setup.Another nice bonus is getting two units in the pack. It’s useful to monitor different areas at the same time, whether it’s for a greenhouse, reptile enclosure, humidor, or just general indoor humidity tracking.Overall, these are simple, reliable little meters that get the job done. If you need an affordable way to monitor humidity and temperature in small spaces, this 2-pack is definitely worth it.

It may not be the most expensive/accurate model but it certainly works. It's a low-power (and low-cost) design, so it will not update in real-time. I estimate it checks the reading every 5-10 seconds. So if you just bought it and the two units show different readings, leave them undisturbed for about an hour and check again.I got these because they are panel-mountable. It's about 40mm diameter. I don't have a set of metric hole saws, so I 3D-printed a bracket that I can attach to a bigger hole.The real test for me was when I was applying polyurethane in my basement shop, and the stuff just wasn't drying. I checked this humidistat, which I'd left on a shelf, and it read about 60% RH. Too high for a shop. I kicked on a dehumidifier. The RH went down to about 53% in about 30 minutes and the polyurethane started to cure a lot faster.A really good purchase for DIY projects. If you want something fancier (i.e. backlit display, faster readings, more features) you're gonna pay for it both in power consumption and dollars. For me, this is perfect. Probably going to get a few more to monitor other parts of the house.

These hygrometers are fairly accurate and easy to read. The are the perfect size for many applications that require a smaller Hygrometer such as curing in Mason jars. They look nice and are very portable. The come with extra batteries and 2-sided tape for mounting if desired. I put both hygrometers next to a known accurate hygrometer and they were within 1-2 percent of the known calibrated unit, however the readings were a little unstable as they fluctuated. They also switch very easily from Fahrenheit to Celsius with just a push of a button. The temperature readings were a bit questionable, but I only needed these to measure humidity. So, if you don't have the cash for a high-end hygrometer and only need a fairly accurate humidity measurement, these are a good choice.

Most of hygrometers only read 20-100% RH, but these read 10-100% RH. Consistency in the reading from one hygrometer to the next is good. I think there was less than 1% RH difference between the four hygrometers I received when placed together.

Both went straight into the filament dry boxes next to the desiccant. They read within a couple percent of each other then my dryer, which is all I need to know when to recharge the beads, and the display is legible even in dim light. Two months in, no drift, no dead unit, no falling apart, which is more than the low-star reviews would have you fear. Only nit is the button cell batteries, plan on replacing them yearly. For a filament shelf this is honest value; for a cigar humidor, buy something calibrated and certified.

It came as a pack of 2 I just opened them and noticed the numbers are different so it is obvious it doesn’t show accurate information and it is too small and has no option to make the number bigger . It is good they send one spare pack of batteries.

Works perfect for my baby iguanas enclosure. I like how it comes with 2...i use one on his cool side and other on the hot side of the tank. Good price accurate readings..I have a mister i set at 75% humidity and it has the same readings as these do

جيد جدا

ممتاز ولاكن بالنسبه للرطوبه ما ادري اذا القراءه اللي يطلعها صحيحه او لا لان مرات احس قراءه الرطوبه خطأ

These are fine little devices for the price, but when they arrived, one had a completely dead battery and the other had no battery at all. Other than that they're OK for the price.

Both are amazing fairly accurate. Just 10 times more expensive than Indian version. Size is small portable. Quality is amazing. Easy to use.
