Ebo-Jager aquarium heaters, are a leading manufacturer of high quality heaters for over 50 years. They were the first to implement a low water level safety switch in order to avoid glass breakage due to thermal shock. All Ebo-Jager heaters come with a heat shield and use 2mm thick (instead of the more usual 1mm) thermal-shock resistant glass. This quality line of aquarium heaters features chrome nickel helical heating coils designed for maximum strength and even heat distribution, a precision bi-stable thermostat, and a 6 foot long double-insulated cord. Temperature is adjustable from 18 to 34°C (or 65 to 93°F) via an easy to adjust control dial with accurate 1° increments.
