More About The Product Accurate Temperature: The precise temperature probe continuously and securely measure the water's current temperature. For tortoise aquariums, a minimum water level can also be used.
Safe To Use: The safety thicker quartz glass tube is resistant to high temperatures and explosion-proof. Injection molding is used to fill the shell with plastic before it is sealed, fully eliminating any potential leakage risks.
Adjusts Quickly:Quickly raises the water's temperature, compact size, and instantaneous heating make it ideal for heating small and medium-sized fish tanks. For operations requiring only one key cycle, the external controller is practical.
Frequently Asked Questions
The listed temperature range is -50°C to 110°C with a control accuracy of 0.1°C. For aquarium use, you will typically operate in the 22-30°C range for tropical fish. The 0.1°C accuracy is sufficient for most freshwater and saltwater setups. Saltwater reefs requiring very tight temperature control (±0.2°C) should verify against a reference thermometer.
These are different voltage and wattage configurations for different heater/chiller setups: 12V-120W is for DC systems or small setups (nano tanks under 50L). 24V-240W suits medium setups. 220V-1500W is for standard mains-powered heaters/chillers in large tanks (200L+). Match the voltage to your heater/chiller input voltage exactly — mismatch will damage equipment.
A digital temperature controller with cooling and heating relay functions controls both. Based on the description mentioning 'automatic shut-off to prevent overheating' and a 'built-in fan,' this unit supports both heating and cooling control — it turns the connected device on or off to maintain the setpoint, regardless of whether that device heats or cools.
The description says 'large and easy-to-read LCD display.' Standard LCD screens are readable from 1-2 meters in normal lighting. In low light, LCD contrast reduces. Some units have backlit displays for nighttime readability — confirm whether this unit has a backlight in the product images.
Yes — this is an inline temperature controller. You plug your heater into the controller's outlet, and the controller cuts power when the setpoint is reached, overriding the heater's built-in thermostat. This is particularly useful if your heater's thermostat is unreliable or you want more precise control.
Aquarium temperature probes are waterproof by design — they are submerged. Standard probe cables are 1-1.5 meters long, which accommodates most aquarium placements. For deep sumps or aquariums placed on high stands, measure the required cable run from the water surface to the controller unit before purchasing.
