STEII Titanium Dual-Circuit Dual-Display Digital Heater
Enhanced Safety, Ultimate Assurance of Quality and Protection
Memory Function
The STEII is equipped with a built-in memory system that automatically saves the last temperature setting in the event of a power outage. Once power is restored, the system immediately returns to the original setting without requiring any adjustments, preventing unnecessary resets and ensuring a consistently stable aquarium environment.
Overheat Alarm System
To ensure the aquarium always remains within a safe range, the STEII is equipped with an overheat alarm system. When the water temperature exceeds 35℃, the system immediately activates an audible alarm, flashes the indicator light, and cuts off the power supply, protecting fish and aquatic life from potential heat-related risks.
Dual-Circuit Safety Cutoff System
The STEII uses a dual-circuit cutoff design that elevates safety to a professional standard. If the primary circuit malfunctions or fails to stop heating when the temperature deviates from the set value, the secondary circuit is activated to cut off power, significantly reducing risks associated with single-circuit failures.
The Only ETL-Certified Aquarium Heater in Taiwan (Certification No. 5010507)
The STEII has passed ETL safety certification in the United States, complying with rigorous international electrical safety standards. Every stage from design to material selection and production follows the highest benchmarks. It is currently the only aquarium heater in Taiwan certified by ETL, specifically designed for large aquariums and professional marine tanks.
Upgraded Dual-Display Design
The STEII features a dual-display screen that simultaneously shows both the set temperature and the real-time water temperature, allowing users to instantly confirm whether the tank environment matches the desired setting. This design is far more intuitive than traditional single-display models.
Durable Titanium Heating Tube
The STEII uses a high-strength titanium heating rod with excellent corrosion and salt resistance. Even after prolonged use in aquariums, it maintains stable performance, with rapid thermal conductivity that shortens heating time and ensures even temperature distribution.
Precision Temperature Sensor
Equipped with a high-sensitivity temperature sensor imported from Japan, the STEII delivers precise and stable readings, effectively preventing sudden fluctuations that may stress fish, plants, or corals. Ideal for tropical fish, planted aquariums, and marine tanks.
