STC-1000 temperature controller - Model: STC-1000; Voltage: 110-220V, 50Hz / 60Hz; Current: 10A; Relay contact: 10A/250VAC; Temperature measurement range: -50C to 99C - Automatic switching: switches between cooling and heating to maintain stable conditions. Ideal for fermentation in incubators and freezers - Temperature testing and calibration: temperature test uses a set value and a delta value; supports temperature calibration function Key benefits - Wide power compatibility across regions (110-220V) and both 50Hz / 60Hz systems - Robust load handling with a 10A relay for common appliances and chambers - Precise climate control with automatic cooling/heating, reducing manual monitoring - Accurate readings with calibration option for reliable temperature management Use scenarios - Home fermentation: regulate a dedicated fermentation chamber, beer or yogurt in a fridge or incubator - Laboratory or food storage: maintain stable temperature in incubators or freezers for samples, reagents, or ingredients - Small scale cultivation: support plant propagation or mushroom cultivation that requires steady temperatures
