Fluval Vuetech E Series Heaters use an advanced digital microprocessor to continuously monitor aquarium water temperature. An internal thermal sensor constantly samples aquarium water temperature for greater accuracy and reliability.
The manufacturer does not state the range that the heater can be set to, merely the actual temperature with high and low alerts on the LED. The Vuetech E Series Heater innovative color-coded temperature alert feature changes LCD screen color if aquarium water temperature varies from the pre-set temperature (Green = Safe Zone, Red = High Temperature Alert, Blue = Low Temperature Alert). The Vuetech E Series Heater has an easy-to-use adjustment lever that allows precision temperature settings in 0.5Â° increments and integrated heater guard offers advanced protection for fish and invertebrates.
