Digital Temperature Controller STC-9100

The STC-9100 is a versatile digital temperature controller featuring dual relay outputs for independent heating and cooling control, making it ideal for precise temperature management in incubators, fermentation chambers, aquariums, greenhouses, and industrial processes. The bright LED display shows real-time temperature readings while the intuitive interface allows easy setpoint adjustment and parameter configuration. With highly accurate NTC sensor probe and adjustable temperature differential, this controller maintains stable temperature within tight tolerances.

Supporting both Celsius and Fahrenheit modes, the STC-9100 offers flexible temperature range from -50°C to 110°C with 0.1°C resolution. The dual relay outputs (heating and cooling) can control external devices up to 10A each, suitable for heaters, coolers, fans, and refrigeration compressors. Features include adjustable temperature differential (hysteresis), sensor calibration, overheat alarm, and delay protection for compressor-based cooling systems. Simple wiring with clearly labeled terminals makes installation straightforward for both hobbyists and professionals requiring reliable automated temperature control.
