## Description

The STE Titanium Aquarium heater series is ETL listed to UL Standards. The STE uses an advanced digital processor that monitors and controls the water temperature in your aquarium. The heating controller receives temperature data from the remote sensor in the aquarium. The remote sensor contains no bi-metallic contacts to arc, corrode or wear out. This allows STE heaters to have precise control, keeping the water temperature stable (± 1°F accuracy) while avoiding wide temperature swings common with low-quality aquarium heaters. The controller displays the current temperature, allowing you to easily make temperature adjustments on the front panel. Temperature can be adjusted by a one degree. STE heaters utilize Redundancy Protection. In the rare occasion one component fails, the second component takes over. This safety feature prevents over-heating of the aquarium, saving your prized aquarium life from harm. The heater is constructed of corrosion-resistant titanium, making it safe for freshwater and marine aquariums. The heater tube is virtually unbreakable and won’t be damaged by bumps from live rock or big fish.
