The electric heating mantle is mainly used for heating laboratory liquids in various technical secondary schools, petroleum, chemical, pharmaceutical, environmental protection and other industries. It uses high temperature resistant alkali-free glass fiber as insulating material, and the resistance wire is sealed in the insulating layer, and then Woven 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 is a reliable heating equipment for laboratories and fine chemical units.
The electronic temperature regulation type (HDM-B type) adopts an excellent non-electric shock electronic Voltage regulation circuit, which has the advantages of longer service life and wider temperature regulation range than mechanical temperature regulation in terms of temperature control. When using, turn on the power switch, then turn the temperature adjustment knob clockwise, the voltmeter will display the working Voltage at the same time, gradually increase the temperature according to the temperature you need, after reaching the required temperature, turn the adjustment knob counterclockwise to make it reach constant temperature the goal of.

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. No flammable, explosive or corrosive liquid or gas can enter the heating mantle. The relative Operating Environment humidity of the electric heating mantle does 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.
