9, low temperature constant temperature bath according to the different structure is divided into ordinary Benchtop, Floor-Standing, small vertical and horizontal;
10. The thermostatic test can be carried out directly in the water tank, or the controlled thermostatic liquid in the tank can be directed to the Miscellaneous equipment through the hose connected to the Miscellaneous equipment using the external circulation function.
Principle
The product realizes accurate measurement and regulation of the liquid temperature in the tank through a high-performance single-chip microcomputer Control system, combined with a self-tuning PID adjustment algorithm and an imported temperature sensor. The Compressor refrigeration system is used to cool down, and the liquid temperature in the tank is uniform through a fully sealed stirring motor. The system has safety functions such as liquid level protection and over-temperature alarm to ensure the stability and reliability of the thermostatic field source.
Applications
Bioengineering, Food, Chemical, Metallurgy, Chemical Analysis, Petroleum and other fields, to provide users with a High Accuracy, controlled, uniform temperature constant field source, research institutes, universities, factory laboratories, Quality control departments satisfactory thermostatic device.
Steps
1. Proper placement and connection according to the device structure (Benchtop, Floor-Standing, etc.);
2. Check the liquid level to ensure that the liquid level protection function is normal.
3. Set the required temperature, time and other parameters through a large-screen backlit LCD screen or two sets of light-emitting digital tubes (the PHDC series can program up to 180 program segments);
4. Start the device, and the system will automatically perform PID adjustment and temperature control.
5. You can choose to conduct thermostatic experiments directly in the inner tank, or connect the hose through the external circulation interface to guide the thermostatic liquid to the Miscellaneous equipment;
6. During the experiment, pay attention to observe temperature fluctuations and alarm prompts.
7. After use, shut down the equipment according to the procedures and perform cleaning and maintenance.
Notice
• Before use, ensure that the liquid level is normal to prevent the heating tube from burning.
• Pay attention to setting a reasonable temperature upper limit and enable the over-temperature alarm function.
• Ensure that the temperature sensor is connected reliably to prevent loss of control due to disconnection.
• Select the domestic circulation or external circulation mode according to the experimental needs, and connect the pipeline correctly.
• Regularly clean stainless steel liners and parts that come into contact with liquids.
• Please follow the instrument manual when operating to ensure safety.
