🍀【Heater Out of Water? Shuts Off and Alarms You Instantly】 Water changes, evaporation, or a curious turtle can push your submersible heater above the waterline — and most heaters just keep burning until the glass cracks. This water heater for fish tanks detects the moment it leaves water and cuts power immediately with an audible alarm. Re-submerge it and heating restarts automatically. Whether you have betta fish, a small tank, or a large setup — this feature prevents disasters.
🍀【3-in-1 Safety: Dry-Burn + Overheat Protection + Max Temp Limit】 Your fish get three independent layers of protection: (1) Dry-burn prevention — auto shutoff out of water, auto restart when re-submerged, (2) Overheat protection — stops at +1°F above set temperature, (3) Max temperature auto stop — will not exceed maximum settable range even if the thermostat malfunctions. Every trigger sounds an alarm.
