Overview
DH40-20 Low Temperature Circulating Bath is one of the BINGLIN brand DH series products. It provides a precise thermostatic, hot and cold controlled standard environment for various laboratory testing and analysis institutions. It can be used as a cold source and heat source for direct or indirect heating and cooling. This model has 0.01 ° C high resolution ， +/- 0.05 ° C temperature fluctuation, which is the right-hand assistant of laboratory personnel.
Features
1. Adopt self-developed temperature control technology, with PT100 and all imported electronic components, to achieve automatic thermostatic control.
2. The software system is convenient to correct the display temperature and the actual temperature error, and the correction resolution is as high as 0.001 ° C to ensure the accurate display.
3. Temperature Stability, PID temperature control can automatically adjust parameters according to the medium, special needs can be manually adjusted.
4. Software Digital Lock Control system settings to avoid misoperation and ensure that the experimental data is correct.
5. Accurate temperature control makes the temperature in the Tank stable quickly.
6. Press the "Power" button to turn off all functions of the instrument, but the natural temperature rise and fall process in the tank is still displayed.
7. It uses an effective fully enclosed Compressor for cooling, with fast cooling speed and multiple protections such as overheating and overcurrent.
8. With a professional domestic circulation system to make the temperature uniform and stable, it can be changed to an external circulation system to establish a second thermostatic field outside the machine or as a cold source to chill down the experimental container outside the machine.
9. With over-temperature protection, over-temperature alarm function, can set over-temperature alarm temperature, over-temperature can automatically cut off the load.
10. Optional RS232 or RS485 interface.
Principle
The Low Temperature Circulating Bath precisely adjusts the working state of the heating and cooling system through an automatic thermostatic Control system combined with the PT100 temperature sensor and PID algorithm to achieve precise control of the temperature in the Tank. The domestic circulation system ensures uniform temperature in the tank, and the external circulation system can output the thermostatic liquid to establish an external thermostatic field or as a cold source.
Applications
Laboratory testing, analysis and research institutions
Steps
1. Connect the power supply.
2. Set parameters such as target temperature and over-temperature alarm temperature as required.
3. Start the device, and the system will automatically control the temperature to the set value and maintain stability.
4. Can use domestic circulation or external circulation function.
5. After the experiment is over, press the "Power" button to turn off the instrument function.
Notice
• Avoid misoperation by unrelated personnel to ensure that the experimental data is correct.
• Pay attention to the over-temperature protection function of the device, which can be set and used for over-temperature alarm.
• When using the external circulation function, pay attention to the sealing and safety of the connecting pipeline.
• The temperature change in the slot will still be displayed after the equipment is shut down, please pay attention to distinguish the working status.
