Meiyingpu 85-1C heating constant temperature magnetic stirrer is a small-capacity, heated magnetic stirrer with stepless adjustable heating power. It has a compact structure, strong stirring power, and is easy to use. It is suitable for laboratory use in various fields.

1. Place the stirrer stably, place the beaker containing the liquid medicine in the center of the disc (i.e. electric stove), and put a stirrer into the beaker. The bottom of the beaker should be flat to avoid affecting the operation of the stirrer;
2. Turn on the power switch, the power indicator light will be on, and slowly adjust the speed knob clockwise. The stirrer in the beaker will stir the liquid from slow to fast. You only need to adjust the required speed;
3. When the liquid medicine needs to be heated, turn the toggle switch on the back of the machine downward, the temperature rising indicator light will turn on, and the electric furnace will be powered on to generate heat. The heating power of the electric furnace is adjusted by the temperature adjustment knob. The scale only indicates the rotation angle;
4. If automatic temperature control is required, the two leads of an electrical contact mercury thermometer (prepared by the user) can be connected to the two terminals at the back of the machine. The thermometer is inserted into the beaker of liquid medicine and fixed on the benchmark. When heated to the preset temperature It will automatically stop heating when the temperature is lower than the preset temperature, and it will automatically resume heating (the temperature rising indicator light goes out) to achieve automatic temperature control;
Note: The electric furnace has a certain thermal inertia. That is, when the electric furnace is heated to the preset temperature, the electric furnace is powered off and the temperature rise indicator light goes out, but the remaining heat will still heat the liquid to raise its temperature, affecting the temperature control accuracy. At this time, the heating can be appropriately lowered. Power, turn the temperature adjustment knob clockwise to increase the heating power, turn it counterclockwise to decrease the heating power;
5. After use, unplug the power supply, clean the surface after cooling, and store it away.
1. The power socket should be well grounded;
2. This machine should avoid being used in humid environments;
3. When the machine is in use, the liquid in the beaker should not be too full to prevent it from overflowing during stirring;
4. This machine cannot be used as an electric stove alone.
