The constant temperature electric heating sleeve is a kind of universal heating instrument in the laboratory. It consists of a hemispherical heating inner sleeve and a control circuit made of alkali-free glass fiber and metal heating wire, and is mostly used for precise temperature control heating of the glass container. It has the characteristics of fast temperature rise, high temperature, easy operation and durability. It is an ideal instrument for precise temperature control heating test.

The constant temperature electric heating sleeve uses the alkali-free glass fiber as the insulating material, and the Cr20Ni80 alloy spring device is placed therein, and the aluminum silicate cotton is insulated by the vacuum-shaped hemispherical thermal insulation body, and the outer casing is injection-molded at one time, and the upper cover is electrostatically sprayed, due to With spherical heating, the heated area of the container can reach 60% or more. The temperature control adopts computer chip as the main control unit, adopts multiple digital filter circuit, fuzzy PID control algorithm, has high measurement precision, small flushing temperature, single-button touch operation, dual-screen display, internal and external thermocouple temperature measurement, controllable Silicon control output, 160-240V wide voltage power supply, with break-proof protection function, fast heating, high temperature, easy operation, durable, is the ideal instrument for accurate temperature control heating test.

Thermostat heating sleeve precautions

1. The thermostat electric heating sleeve should have good grounding.

2. When used twice, white smoke and odor appear in the sleeve. It is normal for the color to change from white to brown and then white. Because the glass fiber contains oil and other compounds in the production process, it should be placed in a ventilated place. After a few minutes, it will be used normally.

3. When the electric heating sleeve of 3000ml or more is used, there is a 吱-吱 sound which is different in the structure of the furnace wire and related to the thyristor voltage regulation pulse signal, which can be used with confidence.

4. When the liquid overflows into the sleeve, please turn off the power quickly, put the electric heating sleeve in a ventilated place, and use it after drying to avoid danger of electric leakage or electrical short circuit.

5. When not in use for a long time, please store the electric heating sleeve in a dry and non-corrosive gas.

6. Please do not empty the stove for heating or dry burning.

7. When the ambient humidity is relatively large, inductive electricity may be transmitted to the outer casing through the insulation layer. Please use the grounding wire and pay attention to ventilation.
