2Electric power:30WHeating power:300W

3Infinite speed regulation:0-1500change/divide Temperature control range: room temperature+10℃~300℃ Accuracy: ±0.5℃

4Large mixing capacity:2000ml

5Bidirectional interval time:30S

4、 Usage method

When using this instrument, first check if all the accessories accompanying the machine are complete, then install the fixtures in order and place the beaker that needs to be stirred in the center of the chrome plate. Add the solution, place the stirrer in the beaker solution, and turn on the power,When the indicator light is on, work begins. The speed control is gradually adjusted from low speed to high speed, and it is not allowed to start directly from high speed to avoid the agitator not being synchronized and causing jumping. Set temperature: PressSETThe key can be used to set or view the temperature setpoint. clickSETThe characters on the digital display start flashing, indicating that the instrument panel has entered the set state. Press△The key setting value increases, press▽The key setting value decreases, long press△Key or▽The key data will change quickly, press againSETThe key instrument panel returns to normal state and the temperature setting is completed.

5、 Precautions

1To ensure, please connect the ground wire when using.

2Heating time should generally not be too long, intermittent use can prolong the service life.

3Medium speed operation can work continuously for 8 hours, while high-speed operation can work continuously for 4 hours.

4Do not heat when not stirring.

5When this instrument is in operation, it should be supervised by a dedicated person to prevent accidents.
