Mini Hygrometer Indoor Humidity Meter Hygrometer Thermometers 6 Pack Humidity Meters Gauge Hygrometer Mini Digital Thermometer Hygrometer with Fahrenheit (℉) for Humidors, Greenhouse, Garden, Cellar

These mini hygrometers are a great value. I picked up a six-pack and tested them side by side in the same room—impressively, all six gave identical humidity and temperature readings, which gave me confidence in their accuracy. They're compact and super lightweight, so I’ve placed them throughout the house, near windows, even in the attic next to a humidifier setup and it does confirm the dehumidifiers reading.The screen is easy to read at a glance, and there’s no complicated setup or batteries to worry about replacing constantly. If you want a simple, effective, and low-cost way to monitor indoor humidity in multiple spots, this little pack is a solid option. No complaints at all!

I picked up this 6-pack of mini hygrometers so I could keep track of humidity in my filament dry boxes. Each unit is small, lightweight, and easy to place or mount. The display is clear and easy to read, even from a short distance.Highly recommended if you want affordable, reliable humidity tracking without taking up much space. Original battery life on the meter varies so you might have to replace them sooner.

They had different accuracy reading in the packaging, but all were about the same. Worked well, nice and compact, but if they get water on them they will read very moist for hours. They feel durable good for the price though.

Great price. These let me track the percent humidity throughout my home to make sure it stays under 60% (the threshold for mold growth). These sensors are really great for getting the information you need for controlling home air quality. If you’re prone to respiratory illness, have asthma, live in a humid climate, or a home with questionable ventilation, buy these. I know these are mainly used for reptiles, but I found them extremely helpful for my own health as well as that of my pet. Apparently our home regularly stays at over 80% humidity throughout, swaying between the low 70s and high 90s % humidity. It means the air is permanently heavy and everything is slightly sticky. Humans generally should aim for the 40-50% range. For asthma, humidity between 30-40% is recommended. This sensor pack let us find out how our behaviors from shower temperature to closed/open windows affects the moisture in the home so we can aim for a healthier balance. It’s the most important tool for staying on top of mold/spores and bacteria in the air. Landed up purchasing a dehumidifier and these sensors are very accurate and in tune with the changes, even if they take a minute or two to adjust. I wish they had a small place for a hook or screw so I could hang them instead of having to find places to stand them up, but so far no complaints.

Works good. I am guessing they are very accurate as they all have the exact same readings when placed together. I used these in my filament box for my 3D printer to watch humidity.

But with 6 you can get a rough reading, and between rooms they'll be relatively accurate.

These work well and just what we needed for our project. Small/not bulky item to show humidity and temp in our house as well!

Very handy. Many uses besides why I ordered them. Great product, price and store.
