Customers say
Customers find the humidity controller works well for both humidification and dehumidification, is easy to set up and use, and consider it a quality product that’s worth the money. The accuracy receives mixed feedback, with some finding it very accurate while others report extremely poor accuracy.

Set It, Forget It, Stay Humidified
Functionality:The Inkbird IHC200 is the unsung hero of our commercial setup. With dual relay outputs, it can handle both humidifiers and dehumidifiers, keeping our space dialed in with impressively accurate readings (±3% RH). Setup is straightforward, the display is easy to read, and once itâs running, it just works â no babysitting required.A reliable, low-maintenance solution for anyone needing precise humidity control.

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.

Works well
I’m quite pleased with this unit, seems to work as advertised and is built sturdily. A minor annoyance is the teeny little manual has type that one needs a microscope to read. The manual, however, is online, I downloaded and printed out at a decently-sized version. The controls to set humidity and other functions are straightforward and well-described. One issue with the manual is that the unit automatically figures out whether one wants to use it to control a humidifier or a dehumidifier, a little confusing at first on how it knows. A more detailed look at the manual gave me the information I wanted. Turns out the unit has to AC output plugs, one to plug in a humidifier, the to plug in a dehumidifier. Theoretically then, one could put a humidifier and dehumidifier in the same room and let them duke it out.

Very good except for the instruction manual
This product works well once you’ve got it figured out, but the instruction sheet is an amateurish translation from some foreign language and very difficult to understand. I’ve used this controller for two years now to cycle a small humidifier on and off in response to the room humidity level and it does well at that, but the instructions need to be rewritten for clarity for English speakers.

A little pricey but worked well for my application
I had an expensive humidifier that worked perfectly except for the humdistat so it would not turn on and off at the appropriate level of humidity. I set the desired humidity level on the device and plugged in the humidifier. This has worked to turn it on and off at the appropriate level. I also checked the humidity reading against other humidistats and it was within a few degrees. Although I felt it was a bit pricey, it worked great for my situation and I was able to revive the costly humidifier.

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!!

Worth the money
Iâve been using the INK-IRD Humidity Controller for a while now, and itâs 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 doesnât 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!

Je regrette de ne pas avoir pris la version wifi, peut être une prochaine fois. D’autres bon matériel, fiable et précis. Je recommande.

Excellent produit et facile à configurer. Me permet de gérer l’humidité efficacement dans ma chambre de fermentation. Il est possible de brancher un humidificateur et un déshumidificateur et gérer à quelle pourcentage l’un ou l’autre est déclenché. Ainsi, je réussis à maintenir une humidité relative stable pour assurer une constance dans la fabrication de salami.
