JJ-3 type temperature control powerbasic stirrer

1. Introduction:

JJ—3 temperature-controlled electric agitator is widely used in large and medium-sized colleges and universities, environmental protection, sanitation, epidemic prevention, petroleum, chemical industry,

Medical and other units. This instrument has good performance, no noise, no vibration; it adopts digital temperature control and the reading is intuitive and obvious. It is a tool that the experimenter needs.

2. Performance:

1. Working power supply: 220V±10V50HZ

2. Machine power: 1060W

3. Stepless speed regulation: starting ~ 2000 rpm

4. Temperature control range: 0~200°C±1°C

3. How to use:

When using this instrument, please first check whether the random accessories are complete, then install the fixed pillars in order, put on the cross connector and adjust the height according to the experimental requirements, install the fixture and motor, put the stirring rod on and rotate Standby. Connect the plug with the corresponding socket on the control box (note: the plug cannot be reversed). Then plug in the power switch, turn on the power switch, and indicate

When the light is on, adjust the speed control knob from left to right (from low speed to high speed) to select the stirring speed you need. When you need constant temperature heating, please turn on the heating switch, the indicator light is on, and the constant temperature indicator light is on, indicating that constant temperature heating can be performed , At this time, the liquid to be heated should be placed in a beaker or flask and then placed on the electric furnace equipped with it for heating operation, while stirring, so that the experimental solution is heated evenly, and the temperature control probe is placed in the solution for measurement The actual temperature of the solution. When the experiment requires a temperature value higher than normal temperature, please turn the "measurement setting" switch to the setting end, adjust the temperature selection knob to the temperature value you need, and then turn the switch to the measurement end to display the temperature value It is the actual temperature of the solution. At this time, the temperature rise indicator is on, indicating that the heater has started to work. When the solution temperature reaches the temperature you set, the constant temperature indicator is on, indicating that it is in a constant temperature state. When the temperature fluctuates, the constant temperature and temperature rise indicators are automatically exchanged. Keep the experimental solution in a relatively constant state. This process is automatically completed without any operation. When not working, the power should be cut off in time. To ensure safety, please connect the ground wire when using. The instrument should be kept clean and dry.

4. Matters needing attention:

1. Pay attention to the correct operation when using the instrument, intermittent use can prolong the life.

2. When not in use for a long time, please wipe it clean and place it in a dry and ventilated place.

3. Please read this manual carefully before use for correct use.
