This is a solid little unit that provides helpful/accurate information. Easy to read numbers and graphs, and even has a light when neeeded! I had no idea how little indoor humidity I had in the winter time until I got this. Now I'm easily able to guage/achieve a more healthy indoor environment. A must have for cooler/cold climates. Would purchase again and am considering giving as a useful gift. Read more

Have needed this forever. Works great, gives me a more accurate read in the house (which is a metal home). Shows temperature and variations. Has easy to read "humidity" section. Did not realize it had a magnet until I put it close and it basically jumped out of my hand to the wall...so I can guess it is a good one...Worth the money. Have not used the bluetooth and probaly will not. Read more

I set this in my humidor and it took a couple hours to reach the rh level of the humidor. I have a couple of other brands in there already so I know what the temp and humidity should be. I calibrated it once it reached the temp and humidity I knew was in there. 3 hours later cigars are 68 temp and 66 humidity. Holding the numbers solid. However, if I leave the door open too long and the rh numbers drop, it will take it a few hours to settle and read the proper rh again. I mean it creeps back up on the display. Nevertheless, it is working very well. Read more

I do wish they had an option that put the temperature in BIG NUMBERS and the humidity in small numbers, so loses one star for that for our needs anyway. Well, it is sold as a hygrometer, not as primarily a thermometer, so... Comparing with an expensive pro thermometer, it was spot on. Read more

Easy to setup and use. Bright display (when activated). Large display characters. Seems well made. Flexible mounting options: integral tilt stand, magnets and wall hanging slots. Does not require or include Bluetooth or WiFi, passive monitoring only, perfect for periodic manual checks of temp and humidity. Using to verify proper operation of home HVAC thermostat temp sensor.

Thermometer/hygrometers are common. I chose this one because the significant digits (current temperature and relative humidity) are large, the rest tiny or absent. There is a color bar and pointer for graphic confirmation of what you already know. There are minuscule trend arrows and unobtrusive high/low values for both readings over the previous 24 hours, but there are no goofy faces or swoopy nonsense. The backlight comes on at a touch, when needed, staying lit for only a few seconds. It's a functional, dignified tool, which for my taste is a thing of beauty. Read more

Review for: SMARTRO SC42 Professional Digital Hygrometer Indoor Thermometer Room Humidity Gauge Pro Accuracy Calibration It is nice looking, just like the photos. The battery compartment was stuck but got it open. There is a table stand on it, just need to not be afraid to break it to pull it out. Very portable. I have no idea about the accuracy of the displays! The cost is cheap. I am uploading an app to see how the room temp and humidity level compares. Update: I have to say, the large numbers can be seen, even when they are dark, from my La-z-boy about 15' away. And I do wear glasses. I am very pleased with this purchase. I have confidence that the readings are accurate (I checked with another indoor therm and it is accurate) I am marking this as a 5 start instead of the 4 star I gave it originally Read more

workes really well, easy to set up. VERY bright so if that's an issue for you than take that into consideration, it does go dark again after a few seconds. Read more
