Profile: Cheri Electrothermal Equipment Limited focus on manufacturing all kinds of heating elements, especially the ones for CO2 regulator, mold equipment and 3D printer. Our armor thermocouple is what we make using a conductor, high-insulation magnesium oxide, jacket, and protection tube made of stainless steel. The basic design of the thermocouple itself, junction boxes, terminal blocks, and a variety of fixed device installations make up the bulk of armored thermocouple goods. We mount our band heaters in a variety of ways and have quick heat transfer and insulating properties.
