This humidify/dehumidify controller from Titan Controls works incredibly well. It maintains 50 +/-5 %RH in a climate controlled experimental chamber with ease. My environment contains a lot of airborne cement dust that is very hard on electronics, but this unit has outlasted and outperformed all others that I have tried. In the winter, I switch it to humidify and plug in a humidifier. In the summer, I switch it to dehumidify and plug in a cheap basement dehumidifier. The setpoint is not entirely accurate but, once calibrated using a normal RH meter, it is very precise. Mine shipped without the control knob, but the manufacturer had one shipped to me within two days. This unit is a bit more expensive than some, but is a high-quality commercial-grade unit that will last a long time in many environments.

Great unit. MADE IN USA!!! Very well made. My only complaint would be that the switch shaft is too short and knob can fall off. I trimmed the back of the knob off so as to sit closer to the face and thus take up more of the shaft.

Please, if your serious about keeping your grow space to a particular humidity do not buy this until. For the cost it simply does not work. I’m trying to dehumidify and the unit ONLY works when setting is on humidify. If I have it set to 60% it won’t turn off until about 75%. If I try setting it any lower than 60 my fan never turns off even when the space hit 42%. Again when the switch is on dehumidify nothing happens!

If your serious, then this is a must. Works reliably when control over your environment is crucial. I live in a part of the US that normally has a RH of 20% or lower. This bad boy makes sure if feels more like the amazon than a desert.

When set at 60% on humidity mode, It will allow the room humidity to fluctuate between 43% and 52%. The dial is not accurate and that gap is larger than I would have liked.. I would have expected a 5% wiggle room but almost 10% at the extremes is kind of a big gap. I came back to let everyone know the ink bird Ihc200 is a 1/3 the price and works spot on with digital read outs!!

Ignore the settings, get the room to you desired humidity and set the dial until the thing you are controlling shuts off (in my case a dehumidifier). Within 2% of my optimal setting which is good enough for me.

Nothing obvious for calibrating the unit. With the analog dial, it's also hard to adjust to any degree of accuracy. But, does the intended job of keeping the room at a fairly constant humidity.

Easy to use. Plug it and set. Thats it. Seems to be about 5% off on accuracy but, no big deal, just offset the level you want by 5%. Lets be honest, this is not a million dollar unit. Does exactly what it says it does.
