Overview
SH23-2 thermostatic Magnetic Stirrer uses brushless DC motor and strong magnetic steel, with stepless speed regulation function and strong stirring force. The equipment is equipped with electric contact mercury-filledthermometer to realize automatic temperature control, Heating power can be steplessly adjusted, and stirring Rotation speed digital display. The shell is made of aluminum alloy, which is suitable for chemical industry, scientific research, teaching and other fields.
Features
1, using brushless DC motor and strong magnetic steel, stable and reliable performance.
2. Rotation speed can be adjusted steplessly, speed regulation performance is good, and stirring force is strong.
3. Equipped with an electric contact mercury-filledthermometer, it can achieve automatic temperature control.
4. Heating power can be adjusted steplessly, Temperature range is wide.
5. Rotation speed is displayed digitally, which is intuitive and clear.
6. The shell is made of aluminum alloy, which is sturdy and durable.
Principle
The equipment drives the internal magnet to generate a swirl/spin magnetic field through a brushless DC motor, which drives the magnetic stirrer in the beaker to synchronize the swirl/spin to realize the stirring of the liquid. The heating part heats up through the heater, and the Heating power is adjustable. When connecting the electrical contact mercury-filledthermometer, the heating circuit can be automatically turned on and off according to the preset temperature to realize thermostatic control.
Applications
Chemical industry, scientific research, teaching
Steps
1. Place the device smoothly, place the beaker in the center of the working plate, and put in the stirrer. Adjust the speed control and temperature speed knobs counterclockwise to the minimum, connect the power supply, and turn on the power switch. Slowly adjust the speed control knob clockwise to the desired Rotation speed.
2. When heating is required, turn the button switch on the back of the machine up, and the heating indicator light is on. Control the Heating power by adjusting the temperature speed knob.
3. If you need automatic temperature control, connect the electrical contact mercury-filledthermometer lead to the rear terminal of the machine, insert the thermometer into the liquid medicine and fix it. The device will automatically stop heating when it reaches the preset temperature, and resume heating when it falls below the preset temperature.
4. After use, unplug the power supply, and clean the appearance and collect it after the equipment is chilled down.
Notice
• Power sockets should be well grounded.
• This machine should be avoided in a humid environment.
• When using, the beaker should not be too full to prevent overflow when stirring.
• This equipment shall not be used as a heater alone.
