SDT 3 digital double relay titanium heater
Safety and quality assurance
Memory Function
In the event of a power outage, the heater's built-in memory chip will restore it to the temperature setting before the power interruption.
High-Temperature Alarm
If the water temperature exceeds 35°C, a high-temperature alarm will be triggered with flashing LED indicator lights and a power cutoff, ensuring the aquarium tank remains in the safest state.
Auto Power-off Function
If the water temperature surpasses 35°C, the LED indicator lights will flash, and the power will be automatically cut off. This function ensures the fish tank stays in a secure state.
Safety Dual-Circuit Control System
An additional backup control system with dual circuits and dual power-off systems. If the temperature exceeds 35°C, the heater automatically stops working, ensuring safety.
Three-Digit Display and Digital Touch Panel
Laboratory-grade three-digit temperature control panel for more accurate temperature sensing and control. Temperature error is ±0.5°C.
CA Temperature Calibration Function
Accurate control of water temperature with the CA button allowing manual calibration of temperature values in 0.1-degree increments.
Indestructible Titanium
Corrosion-resistant, rapidly heating titanium tube to ensure the safety of aquatic life and surrounding equipment. Specially treated surface for even heat dissipation, suitable for both marine and freshwater aquariums.
