The electric heating mantle is a kind of general heating instrument in the laboratory. It consists of a hemispherical heating inner sleeve and control circuit composed of alkali-free glass fiber and metal heating wire. It is mostly used for precise temperature control heating of glass containers. It has the characteristics of fast heating, high temperature, easy operation, and durability. It is the most ideal instrument for accurate temperature control heating test.
The electric heating mantle is made of non-alkali glass fiber as the insulating material, the Cr20Ni80 alloy wire spring is installed in it, and the aluminum silicate wool is insulated by the vacuum-shaped hemispherical insulation body. The outer shell is injection molded at one time, and the upper cover adopts the electrostatic spray molding process. Due to the spherical heating, the heated area of the container can reach more than 60%. Temperature control adopts computer chip as the main control unit, adopts multiple digital filter circuits, fuzzy PID control algorithm, has high measurement accuracy, low flush temperature, single-touch operation, dual screen display, internal and external thermocouple temperature measurement, controllable Silicon control output, 160-240V wide voltage power supply, and with the function of disconnection protection. It has the characteristics of fast temperature rise, high temperature, easy operation, and durability. It is the most ideal instrument for accurate temperature control heating test.
There are two types of heating mantle manufactured by ZZKD laboratory equipment: ZNCL laboratory heating mantle and ZKCL heating mantle. Their capacity is between 2000ml and 20000ml. PID intelligent operation control and burnout protection are more accurate, convenient, fast heating balance, fast heating, temperature up to 380 ℃.
