Overview
The 94-2 thermostatic Magnetic Stirrer is driven by a brushless DC motor and has stepless speed regulation, mechanical timing and stepless adjustable functions of Heating power. The mercury-filledthermometer of the power distribution contact can automatically control the temperature, which is suitable for chemical industry, scientific research, teaching and other fields.
Features
1. Driven by brushless DC motor
2. Stepless speed regulation function
3. Mechanical timing function
4. Heating power stepless adjustable
5. Equipped with electric contact mercury-filledthermometer to achieve automatic temperature control
Principle
The magnetic stirrer swirl/spin is driven by a brushless DC motor to realize the stirring function. The heating system heats the liquid through the heater, and cooperates with the electric contact mercury-filledthermometer to achieve automatic temperature control. When the temperature reaches the preset value, the heating is automatically stopped. When it is lower than the preset value, the heating is automatically resumed.
Applications
Chemical industry, scientific research, teaching
Steps
1. Place the equipment smoothly, put the beaker in the middle of the workbench, put in the stirrer, adjust the knob to a minimum, plug in the power supply, and turn on the timing switch
2. Slow swirl/spin speed knob, so that the stirrer rotates from slow to fast to the desired speed
3. When heating is required, turn the rear button switch down and adjust the temperature control knob to control the Heating power
4. When automatically controlling the temperature, connect the electrical contact mercury-filledthermometer, insert the thermometer into the liquid medicine and fix it, and automatically stop heating when the preset temperature is reached.
5. Note that the maximum surface temperature of the heater exceeds 300 ° C, and the temperature that the liquid medicine can reach is inversely proportional to its amount
6. Unplug the power supply after use, and clean the appearance after chilling down
Notice
• Power sockets should be well grounded
Avoid use in humid environments
• The beaker should not be too full to prevent overflow during stirring
• Not to be used as a heater alone
