KT3200 Temperature and Humidity Controller

The Ketotek KT3200 is a compact, dual-stage temperature and humidity controller ideal for growers looking for precise, automated climate control. With two separate relay outputs, it can control both heating and cooling devices simultaneously — meaning it’s perfect for maintaining consistent grow room conditions throughout the day and night. With a bright digital display that’s simple to program, you can easily set target ranges, adjust hysteresis, and enable time delay functions. Whether you’re growing in a small tent or an entire room, the KT3200 performs reliably, is easy to use, and comes with just enough customization to ensure your plants thrive through every stage of your grow. Consider pairing it with the Air Quality Monitor Indoor CO2 Detector from Ketotek if you need to monitor CO2 along with temp and humidity levels.
