ZNHW electric heating sleeve intelligent constant temperature digital display

The electric heating sleeve is made of alkali free glass fiber as insulation material, with Cr20Ni80 alloy wire spring installed inside. It is insulated with a hemispherical insulation body formed by vacuum shaping with aluminum silicate cotton. The shell is injection molded in one go, and the upper cover adopts electrostatic spraying technology. Due to the use of spherical heating, the heating area of the container can reach more than 60%. The temperature control is controlled by a computer chip as the main control unit, using multiple digital filtering circuits, fuzzy PID control algorithm, self-tuning function, with high measurement accuracy, small temperature flushing, single key touch operation, dual screen display, internal and external thermocouple temperature measurement, thyristor control output,~160-240V wide voltage power supply, and has a break protection function. It has the characteristics of fast temperature rise, high temperature, easy operation, and durability. The sentence is:.ZNHW electric heating sleeve intelligent constant temperature digital displayIt is an ideal instrument for conducting precise temperature control heating tests.

【 Precautions 】

1. The instrument should have a good grounding.

2. When used for the first time, white smoke and odor may appear inside the sleeve, and the color may change from white to brown and then back to white, which is a normal phenomenon. Due to the presence of oil and other compounds in the production process of fiberglass, it should be placed in a well ventilated place and can be used normally after a few minutes of disappearance.

3. When using an electric heating sleeve with a capacity of over 3000ml, there may be a squeaking sound due to differences in the furnace wire structure and related to the controllable silicon voltage pulse signal. You can use it with confidence.

4. When liquid overflows into the sleeve, please quickly turn off the power, place the electric heating sleeve in a ventilated place, and wait for it to dry before use to avoid the 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 place.

6. Please do not use empty heating or dry burning.

7. When the environmental humidity is relatively high, there may be induced electricity transmitted through the insulation layer to the shell. Please ground the wire and pay attention to ventilation.
