1. Widely applied to colleges, petrochemical industries, medicine, and environment protection institutions for liquid heating.
2. It uses high‑temperature alkali‑ glass fiber as an insulating material, seals the resistance wire in the insulating layer.
3. The product has the advantages of large heating area, fast heating, good heat preservation effect, unclear flame, and not easy to touch glass ware.
4. Using advanced non‑electronic electronic voltage regulating circuit, compared with mechanical temperature regulation, it has a long service life and a large temperature regulation range.
5. The electric heating mantle has the function of voltage stabilization, which is the most ideal heating equipment for laboratories and fine chemical devices.

Specification:
Item Type: Heating Mantle

Size: Approx. 500ML: 200 x 165mm/7.9 x 6.5in, 1000ML: 260 x 200mm/10.2 x 7.9in

How to Use:
1. The electric heating mantle has a voltage stabilization function, turn on the power switch, and the switch indicator light is on.2. Turn the knob, the work indicator light is on, adjust the knob voltage to control the temperature, and achieve the purpose of constant temperature.3. At the beginning, the voltage should not be adjusted too high, and the temperature should be increased slowly, otherwise the heater may be damaged if the temperature is too high.
