CHIJIU/Meiyingpu 08-2G thermostatic Magnetic Stirrer 5L/150 ℃ with timing

08-2G

Thermostatic Magnetic Stirrer

Max. stirring Capacity 5L, Temperature range RT +~ 150 ℃, temperature control accuracy +/- 1 ℃, Timer Range 0~ 250min, stirring speed 1500rpm, timing accuracy 1 minute, speed ratio 10:1, motor torque 20mN · M.

Product Description

The 08-2G constant temperature magnetic stirrer is controlled by a single-chip microcomputer. It is an improved version of the company's 08-2 constant temperature magnetic stirrer. It has changed the old tradition of using the potentiometer knob to set the stirring speed, heating temperature, Timer Setting, etc., maintaining brushless DC motor drive, stable speed, accurate temperature control, and more convenient use.

Temperature Control Features

08-2G constant temperature magnetic stirrer adopts dual automatic temperature control of Heating Plate temperature and liquid temperature. Due to the large condition variables used by users, 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, and the amount of stirring , set the temperature high-low and so on. Both will affect the temperature control accuracy, so this machine is set with a temperature difference coefficient from 1 to 250, which can be set by the user.

Instructions

1. Place the stirrer stably, connect the power cord, connect the temperature sensor to the two terminal posts 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, insert the temperature sensor into the liquid medicine, this The machine does not set the power switch, you can directly plug in the power plug, 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 + (liquid set temperature - liquid measured 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 temperature difference value is set according to the amount of stirring, the set temperature of the liquid, the size of the direct contact area between the bottom of the container and the Heating Plate, and other factors.

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 08-2G constant temperature magnetic 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 at the original stirring speed setting.

13. Except that the stirring speed of this machine can be adjusted under the working state, when other data needs to be newly set, the stirring key needs to be turned off first, and the data can be reset when pressing the setting key to an indicator light that needs to be reset;

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

15. When the stirrer stops running, the power consumption is very small. If the time is short, it is not necessary to unplug the power supply.

Precautions

1. The power outlet should be well grounded;

2. When the machine 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;

friendly reminder

1. Someone must be responsible when the 08-2G constant temperature magnetic stirrer is working, just in case.

2. Faults such as leakage caused by corrosion and moisture are not quality problems and are not covered by the warranty.

3. Do not pull the power cord hard.
