Product Details
✓Dual‑Independent Chips: Each chip runs independently. If one chip fails, the other can still maintain proper heater operation.
✓PID Control: Delivers precise temperature accuracy of ±0.5℉ with variable‑frequency heating. As water temperature nears your set value, heating output gradually reduces. Upon reaching the target temperature, it runs at low 50W power for energy‑saving maintenance.
✓Dual Low‑Water Cutoff: The heater auto‑shuts off and shows "Er" error code when the water level drops too low. Dual water‑level sensor design protects the heating element from dry‑burn damage caused by insufficient water level.
✓Dual Overheat Protection: Two independent temperature controllers are built inside. The heater automatically shuts down at high temperatures to achieve anti‑runaway heating and protect your fish from overheating.
✓PTC Ceramic Heater: Compared with nickel‑chromium wire heaters (quartz & titanium heaters), it delivers faster heating speed and more stable heating performance. Under identical operating conditions, the PTC ceramic heater provides higher temperature accuracy and helps prevent dangerous temperature spikes caused by device malfunction.
