Advanced Temp Control

The HPC series uses an advanced digital processor that works to maintain a stable and accurate temperature in your aquarium. The external remote sensor helps to avoid interference from proximity to the heating element and has no bi-metallic contacts to arc, corrode, or wear out, allowing the heater to maintain precise and accurate temps. The built-in display allows at-a-glance temperature checks, and the temperature adjustment button is located externally on the power cord so you don’t have to get your hands wet to make adjustments.


Advanced Temp Sensor

The remote sensor also functions as an automatic power cut-off switch. If the water level drops too low and exposes the temp sensor to air, the power to the heater tube is turned off. This prevents accidental over-heating due to a loose sensor reading room temps.


Heaters are by far one of the most important pieces of equipment on any reef tank. Finnex has been making high quality, compact electric aquarium heaters for years and allows you to create a safe and very stable temperature within the tank.
