Intelligent Temperature Control Contact Points: Temperature control range -40℃~120℃/-72°F~176°F, temperature control accuracy ±1%. The detector automatically senses temperature and sets start and stop temperatures to allow the heater or cooler to function according to programming. Safety Material: Power supply 16A/230V, 3680W.μ, with PC flame-retardant housing, which is durable and long-lasting, has excellent impact resistance, higher safety factor, and has passed multiple safety tests, making it safer to use. Multiple Modes: Temperature Control Mode, F01-F04 Mode, F01 Cycle Time Control Mode, F02 Time-Set On Mode, F03 Time-Set Off Mode, F04 Time-Set Switch Mode. Time can be set from 0 to 99 hours and 59 minutes, and temperature calibration is supported. Reset function. Data storage function, saves all set parameters after power failure. High-Sensitivity Sensor: Equipped with a 1.7m NTC10K/B3950 temperature sensor, which is highly sensitive and supports temperature calibration. It's long enough to meet various working environments. Application: Often used in temperature control systems for plant cultivation, incubation, aquariums, greenhouses, incubators, glass containers, refrigerators, fermentation, heating plates, etc.
