Overview
SH21-1 thermostatic Magnetic Stirrer uses brushless DC motor and strong magnetic steel to achieve stepless speed regulation and good mixing performance. Equipped with electric contact mercury-filledthermometer can automatically control the heating temperature, Heating power is stepless and adjustable, and the shell is made of aluminum alloy casting, which is 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. The shell is made of aluminum alloy casting, with a strong structure
Principle
The brushless DC motor drives the strong magnetic steel to generate a swirl/spin magnetic field, which drives the stirrer in the beaker to rotate to realize the stirring of the liquid medicine. The heating system heats up through the heater, and cooperates with the electric contact mercury-filledthermometer to realize automatic temperature control. When the temperature reaches the preset value, the heating is automatically stopped, and the heating is automatically resumed when the temperature decreases.
Applications
Chemical industry, scientific research, teaching
Steps
1. Place the Stirrer smoothly, place the beaker in the center of the working plate, put in the stirrer, adjust the knob counterclockwise to the 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 rear terminal of the machine, insert the thermometer into the liquid medicine and fix it, and reach the preset temperature for automatic temperature control
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. Can not be used as a heater alone
5. Pay attention to the influence of heater thermal inertia on temperature control accuracy, can be appropriately adjusted Heating power
