A compact digital temperature controller with a 3-digit LED display and 10A relay output. Set your target temperature and the relay activates when the threshold is exceeded, then d eactivates when the temperature drops 2°C below the setpoint—perfect for heating or cooling control applications. Includes a waterproof NTC temperature probe for reliable sensing in various environments. Key Features 3-Digit LED Display – Clear temperature readout 10A Relay Output – Normally open, closes when temperature exceeds setpoint High Precision – ±0.1°C accuracy with 0.1°C control resolution Wide Range – Measures -50°C to 110°C Waterproof Probe – NTC sensor (10KΩ, 0.5% accuracy) included 2°C Hysteresis – Prevents rapid relay cycling Specifications Power Supply – 12V DC Relay Rating – 10A Temperature Range – -50°C to 110°C Accuracy – ±0.1°C Refresh Rate – 0.5 seconds Dimensions – 48.5 × 40.1 × 15.8mm Power Consumption – ≤35mA (static), ≤65mA (relay active) Operating Environment – -10°C to 60°C, 20-85% humidity Ideal For Incubator and terrarium temperature control Brewing and fermentation Aquarium heater control Fan or cooling system automation 3D printer heated bed control Show more
