How to use Heat Collecting Magnetic Stirrer

Heat Collecting Magnetic Stirrer is a new digital speed collecting stirrer developed according to the problems found by the majority of users in the process of using the traditional DF-101S heat collecting stirrer.  It has been promoted and tested in university laboratories.  Its temperature control effect is good, the speed adjustment is intuitive, and the speed is digitally displayed.  It has solved the problem that the speed can not be accurately calculated for many years, and has been well received by users.

Use of Heat Collecting Magnetic Stirrer:

Turn on the power of the magnetic stirrer, the cup is ready, open the cover of the stainless steel container, place the cup in the middle of the stainless steel container, add thermal oil or silicone oil to the stainless steel container to the appropriate height, and put the stirrer into the cup solution.  Turn on the power switch, the indicator lights up, rotate the speed regulating potentiometer clockwise, and stir the speed from slow to fast.  Adjust to the required speed.

To heat, connect the temperature sensor probe, clamp the probe on the bracket, move the bracket to insert the temperature sensor probe into the solution not less than 5 cm, but can not affect the stirring, open the temperature control switch, set the required temperature, according to the temperature control instrument +, - set the required constant temperature, the digital display value is the actual temperature in the cup, heating stop, automatic constant temperature,  Heat collecting magnetic stirrer instrument can be continuously heated constant temperature for a long time.

If the stirrer jumps during the operation of the stirrer, please turn the speed control knob counterclockwise to lower the speed or turn off the power and then turn it on again.  The speed can be adjusted from slow to fast.

Due to unpredictable situations in the heating experiment, personnel should not leave their posts during the experiment.

Heat Collecting Magnetic Stirrer temperature control method:

One is the electric contact mercury temperature measurement.  The other is to use a sensor (electric couple) temperature control, during the use of the electrical contact mercury and sensor end are to be put into the measured liquid, the other end is connected with the machine, in the temperature control process, when the liquid temperature is lower than the set temperature, the heating plate begins to heat, when the liquid temperature reaches the set temperature, At this time,  the electric contact mercury thermometer or sensor transmits the signal to the magnetic stirrer host, at this time the heating disc stops heating, when the temperature is lower than the set temperature again, the heating disc continues to heat, which is the principle of temperature control of the magnetic stirrer.
