The heating temperature can reach 380℃, the hemispherical internal heating heater has a large heating area. High-sensitivity temperature sensor, digital display type, equipped with high-sensitivity temperature sensor. Alkali-free glass fiber, the inner tank is made of high-temperature resistant alkali-free glass fiber material, which is not easy to damage the glassware. It has high thermal efficiency, fast heating, and no open flame. It can be used with confidence. Multi-hole heat dissipation, continuous use, bottom heat dissipation port design, does not affect the appearance, fast heat dissipation, and does not affect work efficiency. Anti-slip pads are set at the four corners to prevent accidents.
