Finnex HMH 300 Watt Digital Heater
The HMH heater series uses an advanced digital processor that monitors and controls the water temperature in your aquarium. The heating controller receives temperature data from a sensor in the heater tube. The internal sensor contains no bi-metallic contacts to arc, corrode or wear out. This allows HMH heaters to have precise control, keeping the water temperature stable while avoiding wide temperature swings found 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 tenth of a degree.
The internal sensor functions as an automatic power cut-off switch. If the water level drops too low and exposes the heater tube to the air, power to the heater is turned off. This 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 features a protective heater guard to prevent aquatic live from accidentally coming in contact with the heating tube.
Maintenance: The out-of-water sensor is located where the heating element meets the cord. Always secure this portion of the heater in a more elevated position than the rest of the heater. Clean and confirm out-of-water sensor is functioning properly every 30 days.Do not use heater if out-of-water sensor is inoperative.
