Goabroa 12 Pack Mini Small Hygrometer Thermometer: Digital Indoor Humidity Gauge Monitor with Temperature Meter Sensor (℉) – Bulk Pack for Accurate Climate Control Review

read none correctly. Place them in a bag with two large 62 Boveda packs every four hours. They show 52 to 65, and only two show over 60. All temperatures vary by five degrees or more. Don't buy pure junk

I really wanted to write a good review about them but I took them out of the box and they were everywhere so I thought of it would be because of the heat so I got out of the box and left them on my island for over an hour and they were everywhere. It would be a good overview if they were all within one to three percent of each other. Not satisfied, I need to know the exact humidity. The only thing I really liked was that I received it a day early. But I want another one, maybe they're out? I…

The lament that values are everywhere is true. I think there might be a way to calibrate them. There were no instructions and some of the words on the box didn't seem to be a good translation. The attached note gives me a feeling that there are good hardworking people working there, working hard and trying to make a living. The units were not expensive. The readings were pretty far off, but I think I can work with that. I'm happy with what I got and wish the best for the people I traded with. I

I like the look and size of the 12m temperature sensor with already running batteries in the devices and extra batteries in the box. Nothing is creased or wrinkled which is a real plus for the packages I've received over the past year which have had two small items packed together in one envelope. I placed a meter in the area I want to measure. I also have at least 4 hydrometer thermometers from different brands in the same area. Guess what? I bought these all through Revain this year, and as…

Needed six hygrometers for my humidors. I bought these 12 packs for an additional $5 thinking half would be incorrect if I'm wrong. I put them through the scientific test. 12 hygrometers and a pack of Boveda 69% placed in a tightly sealed Tupperware container. I took two readings from each hygrometer per day for four days. The hygrometers were gently shaken and changed position between each measurement. The results really surprise me. 96 individual measurements were taken, ranging from 66% to…

Bought these for extra humidity/temperature reading for my cigar humidors. Liked the size and simplicity. They all read differently out of the box. This is to be expected as it is 12 pcs. Basic hygrometer that must be checked for accuracy as standard and marked for calibration. How: Take a bottle cap. Fill it with table salt. Add a few drops of water (do not fill above the salt line - not a mush). Place the hygrometers and lid in an airtight container or good ziplock bag for 24 hours. Note the…

These are great no frills hygrometer/thermometers for a variety of uses, but I chose them to monitor the humidity in and around my guitar cases. The fancy ones sold by musical instrument and instrument dealers use the exact same hygrometer/thermometer probes they do, but they cost many times more than those that cost per unit simply because they come in prettier packaging. I literally got 12 of them for the price of ONE of the fancier ones and I'm pretty sure they're just as accurate. I placed…
