Mini Hygrometer Thermometer Digital Indoor Humidity Gauge Monitor with Temperature Meter Sensor Fahrenheit (℉)

Actually the differences in each device in only 1-2 %(+or -) . Ive placed several of these around the house and used then to correct the reading on my analog hygrometers. I think this is a great product to have in the house especially during winter months when humidity values in the house can get to 20% and lower. I try to keep the humidity at 40%. Helps sinuses and one feels warmer at lower temperatures. I use a steam vaporizer. During cold weather I can put 2 gallon of moisture in the air especially if the outside temperatures are below 30 degrees.

These help me alot and I keep getting more. Love there little size and accurate reading.

This product easy to use. Some angles the numbers look like all 8s. I had to mount it whit double side tape while not bocking the battery port. Overall, it is a great device for my cigar box and small enough that it doesnt take up a lot of room.

I love using these for my humidoir. I use two of them and they have been pretty accurate. Quick response too.

It west geat.

Amazing

I order a few .one of them doesn’t work unfortunately

Great size, nice and small Only used it for a short time so am not sure about battery life yet

Small, but very easy to read

I got this to keep in the case with a mandolin. Its not an expensive instrument, so Im not rabid about accuracy. I dont have anything to check it against, but if its within a couple of percentage points, thats all I need. And Ive no reason think its less accurate than that. It comes to a reading pretty quickly. First time I checked it I learned that I was probably overdoing humidification a bit. Good thing to find out. I give accuracy 4 out of 5 only because I dont know. The size is good for keeping in the case of a small instrument like a mandolin, violin, or ukulele. I havent had it long enough to be able to speak to battery life. It came with batteries installed, and two extra ones - a nice touch, unless its indicative of short battery life. Time will tell. I give battery life 4 out of 5 because I dont know yet. The display is easy to read. The readout shows both temperature and humidity, with humidity the most prominent, which is what I want in this case (if youll pardon the expression). The temperature readout is in Fahrenheit. The box indicates that its a Fahrenheit sensor, so no changing it Celsius. At the price, I wouldnt really expect that. Because its not explicitly sold as a musical instrument case hygrometer, its significantly less expensive than those that are. Ill probably be buying another one.
