Overview
DH30-20 Low Temperature Circulating Bath is one of the BINGLIN brand DH series products, which 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 directly or indirectly for heating or cooling. This model has 0.01 ° C high resolution ， +/- 0.05 ° C Temperature Fluctuation, which is the right assistant of laboratory personnel.
Features
1. Using self-developed temperature control technology, with PT100 and all imported electronic components, the software system can correct the display temperature and the actual temperature error, and the correction resolution is as high as 0.001 ℃.
2. Temperature Stability, PID temperature control can automatically adjust parameters according to different media, special needs can be manually adjusted.
3. The software digitally locks the setting values of the Control system to avoid misoperation and ensure that the experimental data is correct.
4. Accurate temperature control makes the temperature in the Tank stable quickly.
5. Press the "Power" button to turn off the function of the instrument, but the instrument can still display the natural rise and fall of the temperature in the tank.
6. It uses an effective fully enclosed Compressor for cooling, with fast cooling speed and multiple protections such as overheating and overcurrent.
7. Have a professional domestic circulation system to make the temperature uniform and stable; can be changed to external circulation system, external circulation pump can output thermostatic liquid to establish a second thermostatic field outside the machine or as a cold source to chill down the experimental container outside the machine.
8. With over-temperature protection, over-temperature alarm function, can set over-temperature alarm temperature, over-temperature can automatically cut off the load.
9. Optional RS232 or RS485 interface.
Principle
The Thermostatic bath achieves precise control and stability of the medium temperature in the Tank through an automatic thermostatic Control system combined with PT100 temperature sensor, PID control algorithm and refrigeration/heating system. The domestic circulation system ensures uniform temperature in the tank, and the external circulation system can pump out the thermostatic medium to provide a thermostatic environment or chill down external equipment.
Applications
All kinds of laboratory testing, analysis and research institutions
Steps
1. Turn on the power supply.
2. Set the target temperature and over-temperature alarm temperature as required.
3. Start the device, and the system will automatically control the temperature to reach the set value and maintain stability.
4. You can choose to use domestic circulation or external circulation mode.
5. After use, press the "Power" button to turn off the function of the device.
Notice
• Avoid misoperation by unrelated personnel and use the software lock function to protect the settings.
• Note that the device has an over-temperature protection function, which will automatically cut off the load and alarm when it exceeds the temperature.
• When using the external circulation function, ensure that the pipeline connection is correct.
• The temperature change in the tank will still be displayed after the device is turned off.
