Overview
DH20-30 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 automatic thermostatic Control system, including self-developed temperature control technology, PT100 Sensor and all imported electronic components.
2. The software system can correct the display temperature and the actual temperature error, and the correction resolution is as high as 0.001 ° C to ensure accurate display.
3. Temperature Stability, PID temperature control can automatically adjust parameters according to different media, special needs can be manually adjusted.
4. The software digitally locks the setting values of the Control system 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 the function of the instrument, but the natural rise and fall of the temperature 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. Have a professional domestic circulation system to make the temperature uniform and stable; 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 Thermostatic bath is adjusted by an automatic thermostatic Control system. The system consists of self-developed control technology, PT100 Sensor and imported electronic components, and uses PID algorithm to achieve accurate temperature control. The refrigeration system uses a fully enclosed Compressor to achieve rapid cooling. The circulation system circulates the liquid in the tank through the domestic circulation pump to achieve uniform temperature, or outputs the thermostatic liquid through the external circulation pump to establish an external thermostatic field. When the temperature exceeds the set safe range, the alarm system will activate the protection.
Applications
Laboratory testing, analysis and research institutions
Steps
1. Turn on the power supply.
2. According to the experimental requirements, set the target temperature and Miscellaneous parameters through the control panel.
3. Start the equipment, the Thermostatic bath starts working, and the refrigeration or heating system runs to reach the set temperature.
4. The domestic circulation function can be used to make the temperature in the tank uniform, or connect the external pipeline to enable the external circulation function.
5. During the experiment, the instrument will continuously display the actual temperature in the tank.
6. After the experiment is over, press the "Power" button to turn off the instrument function (the temperature change in the tank can still be displayed at this time).
7. Disconnect the power supply.
Notice
• Please read the instructions carefully before use to ensure operation in a suitable environment.
• Power supply voltage meets equipment requirements and is well grounded.
• Temperature range of the medium in the tank should be selected and the liquid level should be kept within the required range.
• When the equipment is running, do not block the entry and exit trends to ensure good heat dissipation.
• Set the over-temperature alarm temperature to prevent the equipment from overheating and damage.
• When setting parameters, pay attention to using the software lock function to prevent unrelated personnel from misusing.
• If external circulation is required, ensure that the piping connection is correct and leak-free.
• When the equipment has an over-temperature alarm, it should be checked immediately and used after troubleshooting.
• Regularly clean the equipment surface and Tank to keep the equipment clean.
• Non-professionals should not disassemble or repair the equipment by themselves.
