Overview
RONGHUA INSTRUMENT DF-4 collector Magnetic Stirrer is a multi-functional experimental equipment with triple heating and stirring functions of dry burning, oil bath and water bath. The instrument has good performance, no noise, no vibration and fast heating. It is widely used in universities, environmental protection, health, epidemic prevention, petroleum, chemical, medical and other units. It is a reliable tool for experimenters.
Features
1. Triple heating stirring function: dry burning, oil bath, water bath
2. Noise-free, vibration-free design
Step 3 Heat up quickly
4.4 station independent temperature control
5. Wide stirring speed range: starting~ 2600rpm
6. PID self-tuning function
7. Timing function
Principle
The Magnetic Stirrer realizes the stirring function by magnetically driving the stirrer to swirl/spin in the container, and at the same time provides thermostatic heating through the heating system. Using PID temperature control technology, the real-time temperature is detected by the temperature sensor, and the Heating power is automatically adjusted to achieve accurate temperature control.
Applications
Universities, environmental protection, health, epidemic prevention, petroleum, chemical, medical
Standards
Single phase AC 220V +/- 10V 50HZ
Steps
1. Check whether the random accessories are complete, install the fixture, and plug in the temperature control Probe.
2. Place the experimental solution in a beaker or flask, put in a stirrer, and place it in the center of the heat collecting plate
3. Plug in the power supply and turn on the power switch.
4. Adjust the speed knob to select the desired stirring speed (high-speed direct start is not allowed)
5. Turn on the heating switch when thermostatic heating is required
6. Temperature setting: Press the SET key to enter the temperature setting mode, press the up/down button to adjust the setting value, and then press the SET key to exit
7. Parameter adjustment: Press and hold the SET key for 3 seconds to enter the internal parameter setting, and adjust the parameters of Lck, Sc, E, P, c, AL, TI and other parameters in turn
8. Timing settings: Press the shift button to turn on the timing in working state, and press the shift button for 3 seconds to enter the timing setting
9. PID self-tuning: Press and hold the down button for 6 seconds to start the self-tuning mode in working state
Notice
• Direct starting at high speed is not allowed, so as not to cause the stirrer to jump out of sync
• Parameter c is a reserved parameter within the system, please do not adjust it
• When the P value is 0, enter the breakpoint control mode, and the system PID will fail
• The ALM light flashes in self-tuning mode, press and hold the down button for more than 6 seconds to exit the self-tuning.
• When timer is set to 0, the timing mode is turned off
