JEDEW Mini Hygrometer Thermometer - Accurate LCD Monitor for Indoor/Outdoor Humidity & Temperature Measurement - Ideal for Humidifiers, Dehumidifiers, Greenhouse, Reptile Environments, Plants & More Review

Not very accurate and as you can see hygrometers are not durable in high humidity rooms. I use them in my snake enclosure where the humidity is kept at around 60-80%. The display failed on one, it was damaged on the other, two still show (inaccurate information) clearly. Invest in something better.

I've had all 4 on my kitchen counter for over 24 hours. Although the temperatures were very correct, all 4 had different humidity percentages. I would have kept it if they were within 1% of each other but the difference was too big. Another thing that bothered me was that they came with a whole and working battery. I was wondering how long the battery will last.

I was hoping they would be perfect for what I need them for but the first one broke when I took it out of the box. The second one looked ok but I put tape on the back and pressed it against the surface to make it stick and it fell apart and broke. I was able to glue the third one fine, but it kept falling off because the sticky layer that came with the product wasn't strong enough to hold it. 4th in the box so far. Plus it comes with extra batteries!

Wanted to try these sensors as they had good reviews and the price was attractive for what you get. Having had them for a month now I can say that they are doing their job adequately. They're accurate, but for some reason it takes a while to catch up with actual humidity and temperature. I know this because I have multiple calibrated devices that control my cigar fridge and desktop humidors. If you're looking for something that will give you accurate readings out of the box, I would look for a…

Rated 4 stars because it advertised a range of 10% to 99% but none of the options were below 20%. Not really a problem considering the price and intended use. I have them in sealed containers with printer filament and silica balls. Humidity should be near zero, but all four read 20%. These are stable displays, even before I put them in the box they didn't change or wobble quickly. Not bad for the price, if you want more accuracy you have to pay significantly more. As I am expanding my thread…

Edited to update: I'm adding and removing other stars. After a month of use, 3 stopped working. New batteries, no repair, they're just dead. The last one will NOT stay at F and keep coming back to C so I know it won't be long. It was a waste of my money and now I'm back hunting, saving your money and looking elsewhere. I thought these 4 packs would be the perfect addition to my daily checks on my reptile enclosures. boy was I wrong. After testing and running several trials with this package, I…

I use them to store 3D printing filaments in closed containers. Basically I just want to know if the desiccant needs to be reloaded. I put all four in the same sealed desiccant container. After 6 hours they showed 19%, 20%, 20% and 22%. So not perfect, but definitely good enough for my purposes. just need a baseball field. After all, you can't expect perfection for $3 or $4. The temp was (almost) within 1 degree and ranged from 74.3 to 75.4 F. So I figured everything was fine. THEN I noticed…

Humidity during COVID 19 is best kept between 40-60%. Articles online indicate that in an arid environment, a lack of moisture in the air can cause a person's moisture emissions (breath, cough, sneeze) to circulate in the air for long periods of time. As a result, even a 1% reduction in humidity can result in an approximately 7–8% increase in infection, while a 10% reduction can double the risk of transmission. Obsessed with the safety and wellbeing of my clients, I purchased these tiny…
