Mini Hygrometer Thermometer 2PCS Mini Digital Humidity Gauge, AikTryee Hygrometer Indoor Humidity Monitor, Temperature Humidity Gauge Meter for Humidors, Greenhouse, Garden, Cellar, Closet, Etc

Both worked fine and accurate

Smaller than I expected (read the description, duh), but that actually works better for my purposes. Two reptile enclosures, two hygrometers in the pack, win! I also appreciate the extra batteries and the double-sided tape. The only issue is that the tape will cover nearly the entire back, including the battery access, and I cant see that going well when I have to replace the batteries. I cut the tape down, but am fairly sure they wont stay stuck for any length of time. And you probably dont want to cover the little holes with the tape, either. Great value for the price!

Works as described. Mine were about 5 degrees off on temperature and humidity. Battery life was meh at about 6 months of 24/7 operation. Decent product for the price. Simple to use and easy to read display.

Works for what I am using it for. (Monitoring 3D printer Filament in storage).

I bought this so time ago and it still works! I can read it perfectly and i believe it gives me a better accuracy than other that i have bought! Will update if anything changes.

I use these in my snake enclosures to monitor tamps and humidity they work perfectly for what I needed. Great little product

If these ever actually die or use up the extra batteries I will buy the same ones as replacements. Just replaced the batteries in one and I’ve been using them for 11 months now. The one with dead batteries has been working overtime. It’s in a basement. In Florida. On waterfront property. So it’s been reading 99% humidity the entire time. The poor little thing is probably as exhausted and overheated as I am! I still have one more set of batteries and the other meter is still going strong. I can’t think of the last $5 I spent that lasted as long as this pair of hygrometers! They are probably not accurate enough to conduct college thesis scientific experiments, but they are CLOSE. And that’s all I needed - to get an idea of how the humidity levels in the basement compared to the rest of the house and how those levels change with the seasons and rainfall. I think the humidity readings are more accurate than the temp readings, which sometimes showed ~4• off from the thermostat BUT my purposes are really for the humidity readings. Totally satisfied with this purchase and will buy same ones again if/when this pair quits or the batteries all die. Probably the extra batteries alone are worth the total cost. #battery life excellent #accuracy close enough #happy customer

Ordered twice at different times, four pieces total. All placed in a sealed container at the same time. After twenty four hours- Relative humidity readings dead on with each other - 70%. Temperature readings within 0.4 degrees, three reading 73.0 degrees, and the fourth reading 73.4 degrees. Conventional thermometers included in the same container read 73.1 and 73.4 degrees. Thats pretty good accuracy/repeatability considering that the units cost less than $2.50 each. For all those complaining about accuracy/repeatability, what do you expect for less than $2.50 each. Youll be spending substantially more for units that use a more accurate sensor and are individually calibrated to give more accurate readings.

I purchased these gauges to keep a watch on the humidity in my guitar cases.

This works well and for the price you cant go wrong.
