The temperature-regulating electric heating mantle is mainly used for heating laboratory liquids in various technical secondary schools, petrochemical, pharmaceutical, environmental protection and other industries. It uses high-temperature resistant alkali-free glass fiber as the insulating material, and the resistance wire is sealed in the insulating layer. Then weave into a hemispherical internal heat heater.
This product has the advantages of large heating area, fast heating, good heat preservation effect, no open flame, and not easy to damage glassware.
This product adopts a professional non-shock electronic Voltage regulation circuit, which has the advantages of longer service life and wider temperature regulation range than mechanical temperature regulation for temperature control. The electric heating mantle has the function of Voltage regulation. Turn the knob to turn on the indicator light or the voltmeter to change accordingly. Adjust the Voltage to control the temperature by adjusting the knob to achieve the purpose of constant temperature. At the beginning, the Voltage adjustment should not be too high, and the temperature should be raised slowly, otherwise the heater will be easily damaged if the temperature rises too high.
1. Since the surface of the glass fiber is coated with grease, the temperature should be raised slowly when using it for the first time. Turn off the power after seeing white smoke, and turn on the power to heat up after the smoke is scattered. Repeat several times until the power is on and there is no smoke before it can be officially used.
2. Flammable, explosive and corrosive liquids or gases cannot enter the sleeve. The Relative Humidity of the Operating Environment of the instrument should not exceed 85%.
3. This product must be grounded, and it must be kept dry and kept away from moisture. If it is wet, you should pay attention to the induction electricity when using it, and don't touch it with your hands. It can restore its good insulation performance after it dries.
