Product review (5 stars): Found what I was looking for.
We live in a ranch house in upstate NY. We use a floor model humidifier without a digital readout. I had 3 different mechanical hydrometers which all read different. This one appears to read accurately. Helps with that delicate balance between enough humidity for health and less water collecting on the windows.
I would also like to be able to hang it on a wall.
I recommend this product
