Product Dimensions:33 x 4 x 4 cm; 372 Grams Material Composition:Titanium Outer Material:Titanium Inner Material:Titanium Colour:As Shown Number of Items:1 Quantity:1 batteries required:No Batteries Included:No Item Weight:372 g With the use of the temperature controller, this heating rod allows accurate thermal control via the intelligent chip and nickel-chromium heating wire for precise adjustments. It is easy to install and use, and great for both fresh water and marine water aquariums, aquaculture, terrariums and hydroponic systems! [UPGRADED] MORE PRECISE TEMPERATURE - Upgraded sensing probes on the top of heater provides more precise induction that reduces temperature error which allows you check the temperature of the aquarium more easily to prevent the difference temperature in water from making the fish sick. [UPGRADED] DURABLE HEATING WIRE - The aquarium heater was changed from the original iron-chromium wire to the nickel-chromium wire to ensure the heater has longer life and precisely control heater temperature. It is extremely durable and stable, and faster heating than normal glass heaters. SAFETY PROTECTION - The fish tank aquarium heater has CE, FCC and ROHS certification. When sensing probe is exposed in the air or detected the water is overheating, the heater will stop heating. Giving your aquarium fish, amphibians, turtles safety protection. EASY TO ADJUST TEMPERATURE - LED digital display temperature that is easy to observe the temperature set by the heater. Using intelligent IC chip for more precise temperature control with less error (1C/2). The touch button ensures that the hand is not wet when adjusting the temperature. SIMPLE OPERATION - The 400w fish tank heater can be used in 70-80gal gallon fresh water and salt water aquariums. Easy to set temp from 20C ~ 34C(68~ 94). Note: Don't expose the heater out of water surface as this may cause damage to the heater.
