Aquarium Temperature Alarm

The Aquarium Temperature Alarm is a dedicated single-purpose device that monitors tank temperature continuously and triggers a loud audible alert — and often a visual LED warning — if the temperature drifts outside a user-configured safe range. It functions independently of heaters, chillers, or controllers, serving purely as an early warning system.

The waterproof NTC probe sits inside the tank while the alarm unit mounts outside. High and low trigger points are set via small dials or buttons, typically spanning 18–34°C. When an excursion is detected, the alarm sounds within seconds, giving the keeper time to investigate and intervene before livestock is harmed.

Essential for overnight monitoring, unattended fish rooms, holiday periods, and any setup with livestock too valuable to risk losing to a silent heater failure.
