CHIJIU SH05-3G Laboratory Magnetic Stirrer 10L/250 ℃

Product Description

The SH05-3G laboratory magnetic stirrer is controlled by a single-chip microcomputer. It is an improved version of the SH05-3 constant temperature magnetic stirrer of our company. Timing time, etc., maintains brushless DC motor drive, stable speed, accurate temperature control, and more convenient use.

Temperature Control Features

The SH05-3G laboratory magnetic stirrer adopts dual automatic temperature control of the Heating Plate temperature and the liquid temperature. Due to the large condition variables used by the user, such as the flatness of the bottom of the container, the size of the contact area with the Heating Plate, whether the container is glass or stainless steel, the stirring volume How much, set the temperature and so on. Both will affect the temperature control accuracy, so the machine is set with a temperature difference from 1 to 300, which can be set by the user.

Instructions

1. Place the SH05-3G constant temperature magnetic stirrer stably, connect the power cord, connect the temperature sensor to the two terminals at the back of the machine, place the beaker containing the liquid medicine in the middle of the Heating Plate, and put a stirring bar, the temperature sensor Insert the liquid medicine, plug in the power plug, turn on the power switch, the speed indicator light is on, and the number shows the original set speed;

2. Speed setting: press the setting button once, the number will flash, use the up or down key to set the required speed, when the speed is higher than 999, the decimal will light up, indicating that the displayed number × 10 times;

3. Time setting: press the setting button once, the time indicator light is on, use the up or down button to set the required time, if no timing is required, set the time to "0"

4. Temperature setting: Press the setting button once, the temperature indicator light will be on, and use the up or down button to set the liquid temperature;

5. Temperature difference setting: press the setting button, the temperature difference indicator light is on, use the up or down button to set the required temperature difference value, the temperature difference value is directly related to the maximum temperature of the Heating Plate, the maximum temperature of the Heating Plate = liquid set temperature + temperature difference value + (set liquid temperature - measured liquid temperature) × 2, in the working state of stirring and heating, press the setting button until the temperature difference indicator light is on, the digital display is the temperature of the Heating Plate, the set temperature difference value depends on the amount of stirring, The height of the liquid setting temperature, the size of the direct contact area between the bottom of the container and the Heating Plate, and other factors are determined.

6. Press the setting button twice, the speed indicator light is on, showing the set speed, and the setting is completed;

7. Press the stirring button once, the stirring indicator light will be on, and the stirrer will run from slow to fast and reach the set speed;

8. Press the heating button once, the heating indicator light is on, heating starts, and the red temperature rise indicator light is on, indicating that the Heating Plate is powered on and heating;

9. The machine can only be heated when it is stirring. When the heating indicator is on, press the heating button again to stop heating. If you press the stirring button again, both stirring and heating will stop;

10. Display the current status: press the setting button, when the speed, time, and temperature indicators are on, it will display the current speed, remaining time, liquid temperature, etc. (when the heating indicator is off, it will display the set temperature). When the stirrer is in the heating state, press the setting button until the temperature difference indicator light is on, and the surface temperature of the Heating Plate will be displayed.

11. When the stirring is stopped, press the stirring key again, and the stirrer will run according to the data set last time;

12. When the machine is in the working state, press the up or down key to adjust the stirring speed. When the key is pressed, the digital display is the required speed for adjustment. After the key is released, the original display state will be restored. The adjusted stirring speed in the working state, The machine cannot be stored, and when it is turned on next time, it will work according to the original setting stirring speed.

13. SH05-3G constant temperature magnetic stirrer except the stirring speed can be adjusted in the working state, when other data needs to be set again, it is necessary to turn off the stirring key first, and press the setting key until an indicator light that needs to be reset can be reset. set the data;

14. When the agitator reaches the set time, there will be an alarm sound;

Precautions

1. The power outlet should be well grounded;

2. When the SH05-3G constant temperature magnetic stirrer is in use, the liquid medicine in the beaker should not be too full, so as not to overflow when stirring;

3. The temperature of the Heating Plate is very high when it is working, so the power cord and temperature sensor leads should be kept away from them, let alone touched;

4. If the machine is not used for a long time, it should be unplugged;
