A brief explanation:
HJ-4 multi-head magnetic heating stirrer is widely used in colleges and universities, environmental protection, scientific research, health and epidemic prevention, medical units. This instrument can be used for comparison with six heads at the same time, and can also be used alone. It has a multi-purpose machine and is an experimental The instrument that laboratory
1. Performance:
1. Power supply: single-phase current: 50HZ, 22V±10%
2. Electric power: 4*25W
3. Heating power: 4*200W
4. Stepless speed regulation: 0-1600 rpm
2. How to use:
When using this instrument, please first check whether the random accessories are complete, then install the fixtures in order, put the liquid to be stirred middle of the chrome-plated plate, then plug in the power plug connected to the instrument, turn on the power, and turn on the instrument. The power switch , the stirring indicator light is on, and it starts to work. The speed is gradually adjusted from low speed to high speed, and the high speed gear is not allowed to start directly, so as to avoid the agitator being out of sync and causing jumping. It cannot be heated when not stirring, and the red indicator is indicated when the heating device is working. There is a switch , and the red indicator light is on when it is not working. To ensure safety, connect the ground wire when using it.
3. Matters needing attention:
1. When you find that the stirrer jumps or does not stir during stirring, please cut off the power to check whether the bottom of the beaker is flat and whether the position is correct. At the same time, please measure whether the current voltage is between 22V-10%, otherwise the above situation will occur .
2. The heating time should not be too long, intermittent use can prolong the service life.
3. It can work continuously for 8 hours at medium speed and 4 hours at high speed.
