Muffle furnace Product Features:

The KDH-4-10 plastic glass fiber content determination box type resistance furnace adopts * technology. The furnace shell is made of high-quality steel plate by folding and welding, and the control box is integrated with the furnace body. Beautiful appearance, avoiding complicated installation for customers. The inner lining is a rectangular integral lining made of high alumina and silicon carbide refractory materials. A spiral heating element made of iron nickel chromium aluminum alloy wire is threaded through the wire grooves on the upper, lower, left, and right sides of the inner furnace lining. Heat up, down, left, and right. The furnace is a sealed structure, and the insulation layer between the inner furnace and the furnace shell is built with refractory fiber aluminum silicate cotton and diatomaceous earth products. The overall design is reasonable, with a long service life. The left side furnace door and smoke exhaust device are easy to operate. Beautiful appearance, exquisite craftsmanship, sturdy and durable, not easily deformed.

Muffle furnace Temperature control:

The KDH-4-10 plastic glass fiber content determination box type resistance furnace with over temperature alarm device adopts an overall design and a user-friendly menu design. It adopts industrial PID self-tuning control technology and dual screen high brightness wide window digital display, with clear and intuitive readings. Microcomputer intelligent control solves the problems of temperature overshoot and temperature control effect. After setting the temperature, the instrument automatically controls the heating output and temperature controlstable Overtemperature alarm and automatic cut-off of heating output. It has the function of timing startup or starting timing at a constant temperature after reaching the set temperature.
