Product Description

This professional-grade aquarium heater combines safety, precision, and reliability in one sleek package. The ETL certification ensures it meets strict safety standards, while the 2mm thick quartz glass tube provides superior heat distribution and durability. The temperature range spans 68°F to 93°F (20°C to 34°C), perfect for both freshwater and saltwater setups.

The included LED thermometer features a high-precision sensor that displays temperatures from 32°F to 122°F (0°C to 50°C) with incredible 0.1°F accuracy. Simply rotate the dial left or right to adjust your desired temperature, and the clear indicator light shows when it's actively heating.

Built with anti-collision, explosion-proof materials, this heater works automatically - heating when water temperature drops below your setting, then shutting off when the target temperature is reached. The double suction cups keep it securely positioned in your tank.
