Overview
ZJB-250S smart laboratory Stirrer is a high-performance device with brushless DC motor and engineering plastic case. It is equipped with a three-core processor intelligent control main board and TFT touch screen. It has functions such as overload and overcurrent protection, self-test, timing, Rotation speed memory, etc. It supports preset Rotation speed, pause at any time, Rotation speed digital display, torque Linear dispersion diagram display and forward and reverse switching, making it easy to operate. The machine has a compact structure, low noise, maintenance-free, can automatically compensate for Rotation speed changes caused by load and voltage fluctuations, built-in overload protection, suitable for long-term high-load operation, and can be competent for high-viscosity medium stirring. It can be adapted to a variety of specifications of working heads.

5. Adopt brushless DC motor to provide strong torque, suitable for stirring and mixing of low to high viscosity liquids.
6. Compact structure, ultra-low noise operation, and maintenance-free.
7. Microprocessor control can instantly compensate for the impact of load and voltage fluctuations on Rotation speed.
8. Built-in automatic overload protection device to ensure long-term continuous and stable operation of the experiment.
9. Can be adapted to a variety of types of stirringrod to meet different experimental needs.
Principle
The Stirrer is driven by the microprocessor Control system to work on the brushless DC motor. The system receives user-set instructions such as Rotation speed and timing through the TFT touch screen, and monitors the running status of the motor in real time. The output torque of the motor is transmitted to the stirringrod through the rotary chuck to disperse, stir or mix the material. The Control system can dynamically detect the Rotation speed and instantly compensate for the Rotation speed deviation caused by load changes or Power supply voltage fluctuations. At the same time, the overload protection circuit ensures that the equipment operates within a safe range. Rotation speed and torque data can be displayed on the screen in real time.
Applications
Biological, food, inks, Spinning & weaving aids, cosmetics, lubricants, pesticides
Standards
Protection Rating: IP40
Steps
Connect the device to the AC 110~ 220V, 50/60Hz power supply.
2. Set the required stirring Rotation speed (0-2000rpm range) and timing time (1-6000min range) through the TFT touch screen or digital knob.
3. Select the appropriate stirringrod (such as four-blade propeller type, etc.) according to the material characteristics (such as viscosity, Processing capacity 0.2-40 L), and load it into the rotary chuck (clamping range 1-10mm) for fixing.
4. Immerse the stirringrod into the container of the material to be processed.
5. Start the equipment to start stirring, and the real-time Rotation speed and torque Linear dispersion can be observed through the screen during operation.
6. Rotation speed can be suspended or adjusted at any time during operation, and forward and reverse switching can also be performed.
7. The device stops automatically after the timing expires, or it can be stopped manually.
