CHIJIU SH23-2 heating thermostatic Magnetic Stirrer 10000ml

product description

SH23-2 constant temperature magnetic stirrer adopts brushless DC motor and good strong magnetic steel, stepless speed regulation, good speed regulation performance and strong stirring power. The distribution contact mercury thermometer can automatically control the heating temperature, the heating power is steplessly adjustable, the stirring speed is digitally displayed, and the shell is made of aluminum alloy. It is widely used in scientific research, teaching and other fields such as chemical industry and **.

Instructions

1. Place the SH23-2 constant temperature magnetic stirrer stably, place the beaker containing the medicinal solution in the center of the work plate (i.e. electric stove), put an appropriate stirrer in the beaker, and place it in the center of the beaker. Place the two Turn the knob counterclockwise to the minimum, connect the power cord, plug in the power, turn on the power switch, the power indicator light will be on, slowly adjust the speed knob clockwise, so that the stirrer in the beaker rotates from slow to fast to stir the liquid until the required The required stirring speed is displayed digitally.

2. When the liquid medicine needs to be heated, turn the button switch on the back of the machine upward, the temperature rise indicator light will light up, and the electric furnace will generate heat. The heating power of the electric furnace is adjusted by the temperature speed knob, and the scale indicates the angle position of the knob.

3. If automatic temperature control is required, the two leads of the electric contact mercury thermometer can be connected to the two terminals at the rear of the machine. The thermometer can be inserted into the liquid beaker and fixed on the benchmark. When the heating reaches the preset temperature, the heating will automatically stop. When the temperature drops below the preset temperature, heating will automatically resume 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, but the remaining heat still heats the liquid to raise its temperature, which affects the temperature control accuracy. At this time, the heating power can be appropriately reduced.

4. After use. The power should be unplugged, cooled and then cleaned and stored.

Precautions

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 beaker should not be too full of Chinese medicine liquid to prevent overflowing during stirring;

4. This SH23-2 constant temperature magnetic stirrer cannot be used as an electric furnace alone.

[Note] Because the manufacturer's packaging may be updated or upgraded, the detailed packaging list shall be subject to the latest standard configuration of the manufacturer.
