This magnetic stirrer is a four-station constant temperature magnetic stirrer driven by a brushless DC motor, with excellent strong magnetic force and stepless speed regulation. The mercury thermometer at the power distribution contact can automatically control the heating temperature, and the heating power is steplessly adjustable. Four The stations can be operated independently.
Instructions
1. Place the stirrer stably, put the beaker containing the liquid medicine in the middle of a working plate (ie electric furnace), put a suitable stirring bar in the beaker, and make it in the middle of the beaker, and turn all the knobs counterclockwise to the minimum , plug in the power, turn on the power switch, the power indicator light is on, turn on the stirring switch of this station (downward), the corresponding stirring indicator light is on, slowly adjust the speed control knob clockwise, so that the stirring bar in the beaker rotates from slow to fast. Stir the liquid medicine up to the desired stirring speed.
2. When the liquid medicine needs to be heated, turn down the heating switch behind the corresponding station, the temperature rise indicator light is on, and the electric furnace is energized to generate heat. The heating power of the electric furnace is adjusted by the temperature speed knob, and the scale only indicates the angle of the knob.
3. If automatic temperature control is required, the two lead wires of the electric contact mercury thermometer (prepared by the customer) can be connected to the two terminal posts behind the corresponding workstation, and the thermometer can be inserted into the liquid medicine in the beaker and fixed on the gauge rod. When the temperature reaches the preset temperature, it will automatically stop heating, and when the temperature is lower than the preset temperature, it will automatically resume heating, so as to achieve automatic temperature control; Note: the electric furnace has a certain thermal inertia, that is, when it is heated to the preset temperature, the electric furnace has been cut off (The temperature rise indicator is off), but the remaining heat will still heat the liquid to make it warm up, affecting the temperature control accuracy. At this time, the heating power can be appropriately reduced.
4. The four stations of the agitator are independent, including the fuse. The user can use one of them or all of them, and the failure of one station will not affect the use of other stations.
5. After use, unplug the power supply, and store it after cooling down and cleaning the appearance.
Precautions _
1. The power socket should be well grounded;
2. The machine should avoid being used in a humid environment;
3. When the machine is in use, the liquid medicine in the beaker should not be too full to prevent overflow during stirring;
4. This machine cannot be used alone as an electric furnace.
