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

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

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.

Simple. Accurate reading within a minute from taking it out of the box. Registered 100% while raining. Not tacky.

Works awesome wish I would've bought another.

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

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".
