Carefree Fish 200 /300 /500 /800W Aquarium PTC Ceramic Heater Dual Independent Chips Dual Overheat Protection Dual Water Level Sensors for Freshwater and Saltwater No Cooking Fish

Features

• Dual Independent Chips:Each chip operates independently. When one of them is damaged, the other chip can still keep the heater functioning properly.
• PID Control:The temperature control is precise, error 0.5. Variable frequency heating. When the water temperature approaches the set temperature, the power of the heating element will gradually decrease. Once the set temperature is reached, the heating element will operate at a low power of 50W to save electricity.
• Dual Low Water Cutoff: When the water level is too low, the heater will automatically stop working and display "Er". The dual water level sensor design ensures that the heating element will not be damaged due to low water levels.
• Dual Overheating Protection:Two temperature controllers are installed inside. When the temperature is too high, the heater will stop working to prevent the situation of cooking fish.
• PTC Ceramic Heater: Compared with nickel-chromium wire heater(Quartz and Titanium heaters) it has a faster heating speed and more stable heating performance. Under the same conditions, the temperature control of PTC ceramic heating rods can be more accurate, and it can avoid the heating rod from malfunctioning due to sudden temperature increase.500W,110~120V/60Hz.68~93.2,for 30~120Gallon fish tank.
