2、 Usage Overview:

Jingda InstrumentHJ-2BThe dual digital display constant temperature and speed measurement magnetic heating stirrer has the functions of digital display constant temperature and digital display speed measurement, abbreviated as the dual digital display dual head magnetic heating stirrer. It is a multi joint heating and constant temperature magnetic stirrer that can perform independent heating and stirring functions. This instrument has good performance, low noise, and significant stirring effect, making it an ideal and essential tool for laboratory technicians. It is widely used in various universities, environmental protection, scientific research, health, epidemic prevention, petroleum, metallurgy, chemical, medical and other units.

3、 Usage:
When using, please first check if the random accessories are complete, then install the fixtures in order, place the beaker that needs to be stirred in the center of the chrome plate, add the solution, and place the stirrer in the beaker solution. Then plug in the power plug of the instrument first, turn on the power, turn on the power switch, and the indicator light will light up to start working. The speed control is gradually adjusted from low speed to high speed, and it is not allowed to start the high-speed gear directly to avoid the stirrer not being synchronized and causing jumping.Set the required heating temperature. When not working, the power should be cut off. To ensure safety, please connect the ground wire when using; The instrument should be kept clean and dry, and it is strictly prohibited for solution to enter the machine to avoid damaging the parts and prevent severe shaking..
4、 Precautions for use:
1When the stirring element jumps or does not stir during stirring, please cut off the power and check if the bottom of the beaker is flat and the position is correct. At the same time, please measure if the current voltage is220V+10VOtherwise, the above situation will occur.
2The heating time should generally not be too long, and the use of gaps can prolong the service life.
3Continuous operation at medium speed8Hours, high-speed operation can work continuously4Hour.
