Overview
H97 thermostatic Magnetic Stirrer uses brushless DC motor to drive stepless speed regulation and strong magnetic steel, strong stirring force, Rotation speed is stable, and has mechanical timing, automatic temperature control and other functions, Heating power stepless adjustable. Suitable for chemical industry, scientific research, teaching and other fields.
Features
1. Driven by brushless DC motor, stepless speed regulation
2. Strong magnetic steel, strong stirring force, Rotation speed is stable
3. With mechanical timing function
4. Automatic temperature control function
5. Heating power is stepless and adjustable
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. During heating, the heater is powered on to heat up, and the Heating power is adjusted through the temperature control knob. With the electric contact mercury-filledthermometer, automatic temperature control can be realized.
Applications
Chemical industry, scientific research, teaching
Steps
1. Place the Stirrer smoothly, put the beaker in the middle of the table, put in the stirrer, adjust the knob to the minimum, plug in the power supply, and turn the timing switch to "ON" or the desired scale
2. Slowly swirl/spin the speed knob clockwise, so that the stirrer rotates from slow to fast to the desired speed
3. When heating is required, switch the rear button down and adjust the temperature control knob to control the Heating power
4. When automatically controlling the temperature, connect the two leads of the electric contact mercury-filledthermometer to the rear terminal of the machine, and insert the thermometer into the liquid medicine and fix it
5. 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, shall not be used as a heater alone
5, the maximum surface temperature of the heater exceeds 300 ° C, the temperature that the liquid can reach when heating the liquid is inversely proportional to its amount
6, heating to the preset temperature when the heater power off, but the residual heat will still be heating liquid, affecting the temperature control accuracy, can be appropriately reduced Heating power
