Features

  • 🐟LED DIGITAL DISPLAY CONTROLLER: ① Displays real-time water temperature or set temperature, three-digit display, water temperature display accurate to 0.1 °F, easy to read. ② 4 kinds of work instructions - Working/Malfunction/ Thermostatic/ Out of water, easy to understand. ③ Child Lock"KEY": need to touch 3 seconds to set the temperature.
  • 🐟RAPID HEATING: Fastest 5 seconds warming, with intelligent circuit board, work with new PTC ceramic thermal conductive material, the outside is wrapped with aluminum material to accelerate heat conduction and protection. Automatically reduces power when approaching the set temperature, fully utilizes thermal energy inertia to smoothly reach the set temperature, saving energy.
  • 🐟INTELLIGENT THERMOSTAT: Over-temperature protection prevents "cooking fish". When the water temp exceeds about 93.5 °F, start alternately flashing EE fault code; and over 97℉, the heater will stop heating automatically. When the water temp cool down to 93℉, the heater will start working automatically. In addition, it has a power-off memory function and no need to set it again.
  • 🐟ANTI-DRY PROTECTION: When the heating rod is exposed to air, display ER fault code and the heater will shut off automatically. When the heating rod is completely immersed in water, it will start working automatically. Effectively extend the service life. (PS: Suitable for freshwater only.)
  • 🐟HIGH-QUALITY MATERIALS: Built-in dual temperature probe, real-time monitoring of water temperature, temperature accuracy of ± 1 °F; high temperature resistant ABS material, no deformation and no softening, explosion-proof and anti-corrosion, no leakage of electricity. Strong suction cup bracket, can stably fix the heater in every corner of the fish tank.

Description

🐡The outer casing is made of ABS material, which and can withstand certain gravity, effectively preventing damage caused by fish. 🌊 Excellent heat dissipation, surface hollowing design, can quickly dissipate heat into the water. 🔍Three-digit digital display, accurate to 0.1 °F, easy to grasp the temperature value and working status. 🌡Double temperature probe prevents the single temperature probe from being damaged and causing no heating or over temperature. 🛡 After the water evaporates, the heater is exposed to the water surface, it will automatically cut off the electricity. 🔥Over-temperature protection system, when the temperature in the tank is over 97 °F will stop heating, to avoid fish from boiling fish due to high temperature. ⏲Automatically remember the temperature, when used after power failure, the temperature no need to set. ☀Through the frequency conversion heating technology, and PTC ceramic materials, it can fully convert electric energy into heat energy, saving energy and safety. Specification: Power:500 Watt Voltage: 110V-120V, 60HZ Power cord length: 5ft+5ft Temp Control Range: 70℉~94℉ Application: 60-120 gallon Note: 1. When using this heating, the heating should be submersible in the water and should not be exposed to the water surface. 2. It is necessary to regularly clean and clean the heating plate. If the heating plate is attached with impurities, the heating efficiency will be reduced. 3. When the aluminum plate inside the heating plate is damaged, please stop using it. 4.

abunda_amazon_reviews I'll start off by saying the good. It does heat well and keep temp fairly steady. The Tank (75 Gallon) is in a heated room (kept around 70) but is close to a outer brick wall of my basement in upstate NY (its cold!). I had 2x 300 watt heaters that just couldnt keep the tank temp above 76.5. I took out one of the 300's and replaced with the 800watt shown and now the tank hovers right at 79.1 to 79.5. The gauge IS off though. I have separate digital thermometer with prob as well as a glass thermometer (as well as a point and shoot thermometer), so I am certain what the actual temp is. The gauge on the heater is set to 83, is reading 82.2 while the actual temp of the water is 79.4 (I just read them as I type this). Not an overly big issue since I know what the temp is, but having an accurate gauge or even a calibration ability would be nice. This is the ONLY reason I took a star off. Other than that, it does what I hoped it would. Set it and forget it heater during a upstate NY winter. Keep in mind this is not a continuous run heater. It turns on for a bit, turns off. It took roughly 2 days to raise temp from 76.5 to 79.5. This I believe is intended so it doesnt stress your fish. All in all, I am satisfied with the heater. If they made it with calibration, it would be a 5 star heater.;;Reviewed in the United States on December 31, 2019;;4.0 out of 5 stars;;Heats well, Temp gauge isn't accurate;;Roy K;;;Wow! look at what Santa Clause brought me for Christmas; the New Hygger 500 Watt Submersible Smart Heater with LED Digital Temperature external readings.
