- Reviewed in Canada on November 12, 2024Verified PurchaseNeeded this to try growing mushrooms... turns out you don't need this. But it's working great.
- Reviewed in Canada on April 13, 2017Verified PurchaseI had some trouble with this unit but I am still using it. The seller sent me a new sensor right away when I started getting sensor errors. This error disables the unit and sounds an alarm until you cycle power. I am not convinced that it was a sensor issue as much as the circuitry not liking driving an inductive load. I hooked the temperature control output to a 120V AC relay coil that I then use to drive 208/120 AC loads. I always use these isolation relays as I don't trust the onboard electronics of these little controllers. This unit would sometimes trip out with a sensor error when the load switched off. Never at any other time...has to be related. I have no schematic to see how these are designed but without that load attached this has NEVER occurred. So I use this as a humidity controller and temperature monitor and I use a separate temperature controller with the isolation relay for temperature control. It has been working for months now. So...does this unit work? Yes it does. And the humidity and temperature accuracy is not bad. I just had issues with it...maybe you won't. It is well built and excellent value for the price.

Reviewed in Canada on March 5, 2025Verified PurchaseExcellent 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.

5.0 out of 5 stars Worth the money
Verified PurchaseI’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!

4.0 out of 5 stars Very good except for the instruction manual
Verified PurchaseThis 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.
