Overview
SH21-2 thermostatic Magnetic Stirrer uses brushless DC motor and strong magnetic steel to achieve stepless speed regulation and strong stirring. Equipped with electric contact mercury-filledthermometer to automatically control the heating temperature, Heating power is stepless and adjustable, the shell is made of aluminum alloy, suitable for chemical industry, scientific research, teaching and other fields.
Features
1. Using brushless DC motor and strong magnetic steel, strong stirring force
2. Stepless speed regulation, good speed regulation performance
3. Heating power stepless adjustable
4. Equipped with electric contact mercury-filledthermometer to achieve automatic temperature control
5. Aluminum alloy shell structure
Principle
The brushless DC motor drives the magnet to generate a swirl/spin magnetic field, which drives the stirrer in the beaker to rotate to realize stirring. The heating system heats up through the heater, and cooperates with the electric contact mercury-filledthermometer to detect the temperature of the liquid medicine. When the preset temperature is reached, the heating is automatically stopped, and when it is lower than the preset temperature, the heating is resumed to realize thermostatic control.
Applications
Chemical industry, scientific research, teaching
Steps
1. Place the Stirrer smoothly, put the beaker in the middle of the working plate, put in the stirrer, adjust the knob to a minimum, connect the power supply, turn on the power switch, and adjust the speed control knob clockwise to the desired Rotation speed
2. When heating is required, switch the rear button up and adjust the temperature speed knob to control the Heating power
3. When automatically controlling the temperature, connect the electrical contact mercury-filledthermometer lead to the terminal, insert the thermometer into the liquid medicine and fix it, and automatically control the temperature when the preset temperature is reached
4. Unplug the power supply after use, and clean the appearance after chilling down
Notice
1. The power socket should be well grounded
2. Avoid use in humid environments
3. The beaker should not be too full to prevent overflow when stirring
4. Not to be used as a heater alone
