Key Features
✔ Smart Safety Alerts & Auto Shut-Off
Built-in dry-run protection and an overheat guard automatically switch the heater off if water runs low or the unit overheats. Audible alarms and LED error codes (“Er”, “EE”, “EU”) provide instant warnings to protect your aquarium and prevent damage.
✔ Precision Temperature Control (15–34°C / 59–93°F)
An external digital controller makes adjustments simple—no need to put your hands in the water. Real-time LED display and indicator lights clearly show the heating status.

At just 10 cm long (4”), this heater fits neatly into nano tanks and tight spaces while still delivering consistent performance.

In the event of a power outage, the heater remembers your last temperature setting—ensuring uninterrupted care for sensitive aquatic species.
