5" Indoor Outdoor Hygrometer/Thermometer, Humidity Gauge Indicator Temperature Humidity Monitor, Analog Hygrometer Humidor (English Version)

Summary: 4-way comparison of different hygrometer models. Evaluation: Two main focus areas: 1) Is it accurate, and 2) can it be adjusted. For the accuracy, I adjust all of the hygrometers outdoor at 90% relative humidity, and then took them inside, and they all tracked to 60%, except for unit #4, which remained at 80%. So three tracked together, and I deemed those "relatively accurate".

Perfect for monitoring humidity in the home! This winter has been brutal and I recently purchased a humidifier to add some moisture back into the air. This little monitor is ideal for keeping an eye on your home’s humidity levels so you don’t overdo it. Best of all it’s analog! I was so exasperated thinking I was going to have to buy another gadget device to plug in somewhere or put batteries in. I was so happy to find this humidity monitor that doesn’t require a thing but a little bit of counter space.

The Uppon hygrometer looks really nice and seems to be accurate. I like the colored zones on the humidity scale. They make it easy to see if the humidity levels are good or not. A thermometer is included, which is nice, but the Fahrenheit scale is not very useful. The Celsius scale is on the top with normal temperature intervals (10, 20, 30, etc). The Fahrenheit scale is underneath that, but it uses the same scale as the Celsius temperatures on top. So the intervals between Fahrenheit temperatures are very awkward. For example, it jumps from 68 to 86. If the temperature is somewhere between these numbers, it's impossible to know precisely what the reading is. They should have put a separate Fahrenheit scale on the thermometer like almost all other F/C thermometers. I took away one star for this flaw. The primary function of the device (hygrometer) is great!

It's large - don't think of one of those small hanging oven thermometers. I can read this thing from across the room! Great buy regardless and serves the purpose in a Florida home.

I bought 2 and they both had the same readings side by side for three days before I sent them other rooms in house…amazing steel enclosure and simple yet sophisticated dials. Totally worth it…have 4 total…love them

Regardless of whether it was calibrated before leaving manufacturer, it has been bounced around in boxes, by forklifts, in containers in ships, by cranes, in warehouses, in trucks and probably more than once by the classic "savage baggage handler." I do not fault the gauge for being off when first opened. I did the salt/water calibration. (1/2 cup table salt; 1/4 cup water; sealed container/bag; stable temperature) Search this process if you are unfamiliar with it. I had to adjust the gauge iteratively. I found small adjustments did overshoot when the gauge was allowed to stabilize again. I finally called it good enough and it is mighty close. I'm an engineer and wanted it perfect, finally had to admit to myself that this is not a lab instrument so do not expect it to be one! The thermometer is adjustable as well. I found it accurate out of the box and did not need adjustment. The relative humidity is large and easily read. The temperature dial is small and not easily read, but I didn't purchase this as a thermometer. The main body is metal, stainless I think. The lens is glass (I tried to scratch and whatever it is is much harder than most plastics.) The stand/foot is plastic and is attached with a phillips head screw. I like the gauge and will buy another one for in the house. The one I bought is outdoors. It is stable on its stand/foot and it does have a keyhole slot to hang (after removing the stand.)

It's getting harder and harder these days to find devices that aren't over-engineered to the point of absurdity. It seems everything needs to be hooked up to your phone via Bluetooth, and needs to be controllable solely via an app of dubious quality and provenance. For the average hydroponic farmer, the last thing you want is to carry your phone into your grow area - hydroponics and delicate electronic devices don't mix. There are other reasons not to use apps, of course, but anyone with an IQ above room temperature is already well-informed about that aspect. Enter this device. No setup, no batteries, no app install, no fiddling around. Just take it out of the box and you now have the power to tell the humidity and temperature at a glance. The large size means you can read it all the way across the room, even through your plants if they're not too bushy. Construction seems fairly solid, though time will tell. I don't have another hygrometer that I can compare it to for accuracy, but the temperature is within one degree Celsius of my infrared thermometer. As I change the humidity in my setup, the hygrometer responds as expected. Overall, highly recommended.

Very useful and accurate without the digital frills.. 5 star product

Works awesome wish I would've bought another.

Excellent product, price and delivery. Thank you and God Bless.

Way bigger than I expected. Oops, should've read the sizing! Works great though and seems like great quality.
