The STC-3028 is a versatile dual-channel digital temperature and humidity controller that allows simultaneous, independent control of both temperature and humidity from a single compact panel-mount unit. Featuring a dual LED display — red for temperature and blue for humidity — it shows real-time measured values and set point values at the same time, giving you a clear, at-a-glance view of your controlled environment without navigating any menus.

With two independent relay outputs rated at 10A each, the STC-3028 can simultaneously drive a heating or cooling device and a humidifier or dehumidifier — making it ideal for incubators, brooders, fermentation chambers, mushroom growing tents, terrariums, aquariums, reptile enclosures, greenhouse automation, cold rooms, laboratory environments and drying chambers. Each channel operates independently with configurable start and stop set points, enabling precise hysteresis-based control for both heating/cooling and humidification/dehumidification modes.

The built-in integrated sensor (1m cable) measures temperature from -20°C to +80°C and humidity from 0% to 100% RH. Both temperature and humidity readings support manual calibration adjustment. The flame-retardant ABS enclosure is panel-mount ready, fitting a standard 71 × 29mm cutout, and is available in DC 12V / AC 230V supply voltage.
