78HW-1
Constant Temperature Magnetic Stirrer
Ⅰ. Brief introduction
This apparatus is our factory's another research result after the HJ-1 Magnetic Heating Stirrer. It is an ideal analysis measurement instrument for heating and stirring liquid, which has the special virtue of auto-controlling constant temperature. It adopts direct current brushless machine, having the characteristics of low crachkling, little mechanical breakdown and steady timing. The agitation machine is made from Fluorine material and all wool and a yard wide alnico, which has the merit of high temperature resistant, antifriction, chemical corrosion resistant and high rotary force. It is very perfect and convenient to carry out mixing in the sealed container.
Ⅱ. Technical index
1. Power source: 220V 50Hz
2. Rotary speed: 0~2000r/min Infinite speed variation
3. Rotating power: 40W
4. Heating power: ≤250W
5. Range of temperature controlled: RT~100℃
Ⅲ. Using methods
1. Close the power source, turn on it, the signal light will lighten. Rotate the timing potentiometer deasil, keep the totary speed of agitation from slow to fast till the rotary speed is required.
2. When temperature controlling is required, controlling heating deasil means warming and controlling it widdershins means cooling, keep doing that till it is up to use. Signal light of heating and constant temperature shows the working status.
3. If the agitation apparatus is jumping when working, please turn off the power source and start it again, keep the speed from slow to fast. And return to its normal stage.
Ⅳ. Precautions
1. Keep it grounded perfectly when using in case of safety.
2. If the agitation liquid splashes in the disk, the component and electric machinery will be burned-out. The power source should be switched off immediately.
3. Keep the machine clean when using, power source should be turned off when not using it chronically, avoiding accident happens.
The products in our factory are ensured to be maintained all the time. (Cost of production will be paid extenuatorily when using improperly or imparing artificially).
