Temp probe wire connects directly to the heating rod, allowing you to measure the temperature in more areas of the tank. Can be used as aquarium thermometer. External controller to set the temp, safer and more convenient. Package comes with suction cups to fix the heater and probe to avoid drifting
• 【High/Low Temperature Protection】SEAOURA's fish tank heater features over-temp protection. When the water temp exceeds the safety temp you set, or the heater or temp probe is exposed to air, it will automatically stop heating and activate an alarm sound to remind you to check the tank in time. 300W turtle tank heater length 26.5cm, power cord length 0.95M+1.5M, temp sensing cord length 0.5M
• 【Effective Heating Thermostat Control】Heater for fish tank will adjust its power according to the temp in the tank. When the water temp in the tank differs significantly from the set temp, the heater will quickly bring the water up to temp. When the water temp in the aquarium is close to the set temp, the heater will work at a lower power to heat up gently and consistently. This saves electricity and avoids sudden temp fluctuations that can cause stress to aquatic life
• 【0.1℉ Precise Temperature Control】Short press the ± button temp can be accurately controlled ±0.1℉/℃, long press the ± button to quickly adjust ±1℉/℃. The aquarium heater has a memory function, which can automatically restore the last set temp after a sudden power failure, no need to reset. Ideal for aquarium hobbyists, perfect for turtles, betta fish, tropical fish, ornamental shrimp
• 【Led Digital Display】The large digital screen synchronizes the tank temp with the set temp, readable accurate and easy adjustment, heating status (red=heating in progress, white=heating completed), and real-time monitoring of the water temp, which prevents overheating/underheating in the aquarium. Fahrenheit and Celsius temp control range: 63-94℉/17-34℃. Convenient for you to monitor the temp of your aquarium tank
• 【Upgraded Safety and Durability】Our submersible heater for aquarium is built-in with thickened quartz heating tubes, and the housing is equipped with sturdy and heat-resistant ABS material, which can withstand cracks caused by impact or water pressure. Pure nickel alloy heating element lasts longer and generates heat faster. Suitable for freshwater and saltwater aquariums, reef tanks and aquascapes
