D'Addario Planet Waves Hygrometer - Humidity and Temperature Sensor

I checked the accuracy of this hygrometer using the Boveda calibration kit, and both of the hygrometers I purchased measured within 1 degree of the test kit. Other hygrometers I've used in my guitar cases were off by 5%. I have one of these in each of my guitar cases along with daddario humidipaks...a must have to protect the guitars from humidity changes.

I hang my ukuleles on the wall and I was concerned that I was allowing them to be damaged by being in an environment that is too dry. I keep this Hygrometer by the ukuleles and know that they are safe in my home environment without keeping them in cases with individual humidifiers. If my humidity dips, I will see it. Now I know that my little musical investments are safe.

I don’t think it’s as accurate as others I had. I have a humidifier/thermometer only 4 feet away, and the RH on the Hygrometer is always less than on the actual humidifier. Makes me wonder?

This works great if you have a guitar or any other wood instrument that needs to be kept at a constant relative humidity (RH)%). This allows me to open my guitar case and at a glance see if the RH is conducive with keeping my guitar in good shape and to avoid possible issues down the road in regards to cracks and glued joints coming undone. It also allows you to check the history to see if during travel it may have been stored in less than ideal conditions. A relatively inexpensive tool that can save you hundred if not thousands of dollars down the line.

The manufacturer packing is poor. Accordingly, when Amazon packs, these, items do not work their way into the final box. In my case, I ordered three humidity control kits. The first one had everything attached on the cardboard. The second one had the digital meter floating around separately in the box as it became dislodged from the proper packing. The third one was missing the digital meter altogether; it was nowhere to be found in the box. Pretty disappointing when you’re getting these for someone for Christmas nearly to find it missing, contacting Amazon and then being told you have to deal with the manufacturer. Then, they want you to do a return, but how do you return something you never received?

Do the weather concerns I never received the item and was issued a prompt refund I went to Guitar Center and got what I wanted but thank you to the seller anyway!

Important accessory for monitoring humidity of your ambient air your guitar is stored in.

I got this for my Taylor 214E DLX, because it's an investment and I want to protect it. The hygrometer does what I need it to do, easy to set up and to read, and the price is good. I'll be buying a second one for my workhorse guitar, an Ibanez Artwood mahogany dread.
