This is a brand new Aquarium Heater
Never used it just opened it to take some photo's
also it's been fully tested and perfectly working fine
Comfort Zone Gold is a glass aquarium heater with thermostat contacts covered with a layer of genuine gold.
Traditional glass aquarium heaters consist of a thermostat, contacts and a heating spiral.
The thermostat controls the aquarium water temperature and, if the need arises, connects or disconnects the contacts, turning the heating spiral on or off automatically
The temperature can be set in the range between 18 and 32°C
Most sensitive elements of the circuit are the contacts - despite using electronic support, due to metal oxidation, their surface is over time subject to gradual decay. That mechanism shortens the life span of the heater and lowers the accuracy of water heating.
The metal is highly chemically inert and is practically not subject to oxidisation.
