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 heat insulator, and the outer casing is injection-molded at one time, and the upper cover is electrostatically sprayed. Due to the spherical heating, the heat receiving 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.

Constant temperature electric heating sleeve use method

1. Insert ~220V power supply, turn on the power switch, the display window will display “K”, the setting window will display “400”, and the electric appliance will be equipped with K-type thermocouple. The Zui high control temperature is 400°C, after 3 seconds, the display window The room temperature is displayed and the setting window displays the last set temperature value.

2. One-button operation, press “▲” or “▼” to decrease the setting. The required heating temperature will be set quickly, for example: 100°C. The microcomputer will determine the heating amount according to the temperature difference between the set temperature and the current temperature, ensure that the temperature is not warmed up once, and maintain the balance between the set value and the display value ±1 °C temperature difference, so that the heating process can be easily completed.

3. There is a rubber plug on the lower left side of the electric heating sleeve, which is used to protect the external thermocouple socket from corrosion and rusting and conduction of the inner wire. When unplugged, the inner probe is disconnected and the machine stops working. If the external thermocouple is used, the plug should be unplugged, the external thermocouple plug is inserted into the socket and the nut is locked, and then the stainless steel probe is placed in the solution for temperature control heating.

4. The electric appliance is provided with a break protection function. When the thermocouple is poorly connected, “1” or “hhhh” is displayed on the display window. When the green light is off, the electric appliance stops heating and needs to be checked before use.
