500W Aquarium Heater, Titanium Submersible Aquarium Heater with LED Display Controller and Adjustable Temperature Sensor, Suitable for 200-350L Aquariums, Fish Heater

HIGH-QUALITY MATERIAL: The HL-999 titanium tube heater is made of high-quality titanium alloy, which is explosion-proof, shatterproof, corrosion-resistant, and more. Compared to quartz heaters, our titanium tube heaters are more resistant to high temperatures and safer. The aquarium heater rod is waterproof (IP68), designed for immersion, and suitable for both freshwater and saltwater aquariums. PRECISE TEMPERATURE CONTROL: The temperature setting range of this aquarium heater is 20 to 34°C (68 to 90°F). The controller displays the set temperature or the water temperature for precise control. Press the "SET" button to display the set temperature. Press the "+" and "-" buttons to adjust the temperature. Press and hold the "SET" button for 3 seconds to automatically switch between °C and °F.
SAFE AND ENERGY-EFFICIENT: The aquarium heater uses intelligent stepped heating and has an automatic shut-off function to maintain a constant temperature. This not only saves energy and reduces power consumption but also protects your fish. If the water temperature exceeds 34°C (97°F), the heater automatically shuts off to protect the water and therefore your fish from overheating.
INSTRUCTIONS FOR USE: This aquarium heater has a power rating of 500W and is suitable for aquariums of 200 to 350 liters. First, immerse the heater and temperature sensor in the water and secure them with the suction cups. Secure the controller tightly and plug it into a power outlet. Then, set the desired temperature. The controller will display the temperature. The red-green indicator light shows whether the heater is still on.
AQUARIUM HEATER WITH TEMPERATURE SENSOR: Our aquarium heater is equipped with a temperature sensor that accurately measures the water temperature. It also allows you to calibrate the temperature difference. Press the "+" and "-" buttons for 3 seconds to calibrate the temperature and compensate for the error! The compensation range is ±1°C to 5°C (34°F to 41°F).

The HL-999 titanium tubular heater is suitable for both freshwater and saltwater aquariums. This aquarium heater features an intelligent heating system, automatic shut-off, constant temperature control, easy cleaning, energy efficiency, corrosion resistance, and other outstanding features. This aquarium heater is a high-quality heating device for aquariums. There are three suction cups that connect the heater to the controller. You can attach it to the side walls or the bottom of the aquarium. The suction cups hold the heater in place and prevent it from floating in the water flow. Compact and space-saving, this aquarium heater leaves more room for your fish. To extend the heater's lifespan, we recommend regular cleaning and maintenance. After a power outage, remove any dirt from the heater's surface. Note: 1. The heating element and temperature sensor must be fully submerged. 2. Turn off the power 10 minutes before cleaning or changing the aquarium water. Wait until the heater has stopped and cooled to room temperature before cleaning or changing the water. 3. Ensure the controller is waterproof to prevent electric shock and leaks. 4. Position the heater so that the water circulates evenly to avoid localized heating that could cause the set temperature to exceed the desired level.
