EDEN 425 AQUARIUM HEATER is different from traditional heaters because electricity is not passed through the bimetallic strip and does not get warm because of the Joule effect. This heating causes an early opening of the contacts in traditional thermostats, before they can “feel” the temperature of the water. As a result of the patented bimetalic technology the thermostat controlling the heater model 425 will open or close the circuit exclusively because of the measured temperature. A special extra pin, integrated in the main setting knob, enables the re-calibration of the thermostat adapting it to the conditions of use and removing any eventual minor discrepancy of temperature between the set one and the one measured with a precision thermostat. It will be sufficient to rotate the post-calibration pin toward + or – (each click corresponds to 1°C) with the proper device inserted to re-set to the value indicated on the main scale of a precise thermometer. The EDEN 425 heater is very robust, it`s submersible and it has double water sealing and offers an easy installation in any aquarium tank by means of the supplied suction cups and holder, suitable for fresh and sea water.
