Thermostatic heating sleeve
  • Detailed introduction

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 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.


De How to use


1. Insert the ~220V power supply, turn on the power switch, the display window displays “K”, the setting window displays “400”, the K-type thermocouple is used for the electric appliance, 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, single-button operation, press the setting to add "▲" or set minus "▼" button will not let go, will quickly set the required heating temperature such as: 100 ° C, green light means warm, green light means stop, 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 rust and conduction inside. 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.
