  • Works very well
This device works very well for my purpose of controlling a dessicant dehumidifier. I use this dehumidifier in a large "box" I built to dry the soundboards for the harps I make. Previous to purchasing this controller I used a humidity/temperature controller that one would attach to a wall in your home or office. This previous controller was awful at gauging the relative humidity in the box or a small room. It required that I constantly keep checking its measured RH to that of a separate, small humidity/temperature measuring device that seems to work very well and can be checked and adjusted fairly easily. This new humidity controller is designed very smartly and its measurements of RH seem to correspond very closely with the small measuring device, unlike the previous controller I used. Also very nice is the fact that I can now have this controller OUTSIDE of the box with the soundboard and dessicant dehumidifier. It has a short cable with an AC receptacle that the dehumidifier can be plugged into, but the actual humidity measuring device is attached to the controller via a fairly long cable. I have the humidity measuring device inside the box, and the AC cord for the dessicant dehumidifier comes out of the box to be plugged into the short cable off of this humidity controller. So I can easily check the RH inside the box without having to open up the box (and thereby raise the RH level). And you can adjust the controller to automatically turn on when the RH reaches 1% to 5% above the desired RH level set on the controller. The only thing I do not like about this device is the god AWFUL english instructions! Can the people at the company in China who make this controller please hire someone who can write clear understandable english, PLEASE!! You will eventually make sense of their nearly non-sensical instructions, but it does take awhile. Just so you know, their "differential" RH level means how far above the target RH the actual RH will get before the device turns on. You can set this differential RH level for 1% to 5% over the target RH level. ... show more

  • Instructions terminology
Controller work as described. It took a little time to program. I think instructions need better explanatory terminology wording describing set up.

  • Great produce, great price, great customer support!!
My wife runs 3 egg hatchers and our Inkbird controller makes environmental control for these a breeze. This unit is very easy to program, very accurate and dependable. The alarm system that notifies us when the humidity is outside our set parameters relieves from having to check the hatchers multiple times a day. We use a baby monitor placed near the controller with the receiver in the house, works great to notify us of any issues. After nearly a year of use, one of our controllers stopped functioning. I contacted Inkbird, they responded quickly and sent us a replacement within a couple of days. THANK YOU INKBIRD!! ... show more

  • Worth the money
I’ve been using the INK-IRD Humidity Controller for a while now, and it’s been a game changer for my setup. It maintains precise humidity levels with minimal fluctuation, which is exactly what I needed. The interface is user-friendly, the build quality is solid, and it was easy to calibrate. I also appreciate the compact design it doesn’t take up much space and fits perfectly into my environment. If you're looking for a dependable humidity controller, this one is definitely worth it! ... show more
