Drains batteries way too fast. I own others and the batteries last for 1 to 2 yrs in them but this one maybe a few months at best.
  • it's accurate.
  • fast battery drain

Overall good unit for measuring humidity

I found the unit to be pretty accurate with measuring humidity. Battery life isn't as long as I would have hoped for it but considering this unit's job it's reasonable.

Planet Waves Humidity Sensor - FAIL
March 9, 2016
Not a good purchase. First off, it is much smaller than it appears in the picture. Secondly, it simply does not work very well. The ONLY thing that seems to work with any accuracy is the thermometer. It came with a dead battery, but a new one did not help that much. Once in a while, the display will BLINK and then revert back to the factory settings, wiping out all of your programmed settings. I use it now as a rough humidity guide and a thermometer.
  • It keeps the temperature somewhat accurately!
  • Too many to list. Don't buy it.

How it works
December 12, 2014
I have two digital hygrometers that vary about 8 points at any given time. I borrowed a third and it varies from the others by another 10%. Obviously I question accuracy. I placed this device in a Tupperware bowl within a bowl with water and left a lid on overnight. The planet waves meter did get to high 90s so it does work on some level. Humidifying a guitar is an exact science. In dry states I think you will rarely get to the magic 45-50% point.
  • Small and easy to Velcro in the case
  • Questionable accuracy.
