3. How It Works:

   • The temperature can be precisely set from 18 to 34 °C and if required recalibrated (±2°). The temperature control accuracy is ± 0,5 °C.
   • The heat is kept at a constant level. The heating function is indicated by a control lamp.
   • The rod is absolutely watertight, can be fully submersed, has an automatic dry run shut-off (Thermo Safety Control), and is suitable for fresh and salt marine water.

4. Innovations:

   • The glass jacket increases the heating surface.
   • It condenses the heat, ensures optimum even heat emission, and forms a heat shield (touching it doesn’t harm the livestock).

5. Manufacture Of The Glass Jacket:

   • The jacket is made from special laboratory glass, which was developed for research purposes. Therefore, it is free from pollutants that could be released into the water. It is resistant to chemical and biological substances. It doesn’t have any fissures and hair cracks through which condensation could penetrate. And even extreme fluctuations of temperature that can occur during a water change do not harm this glass.
