Overview
DADI CHD-0506 Low Temperature Circulating Bath is a precision thermostatic device suitable for biological, chemical, physical, plant, chemical and other scientific research fields. The chassis of this product is made of cold-rolled plate spray, the liner is made of stainless steel, and the foaming agent is used to keep warm, resulting in a strong and reliable structure. Its core is controlled by a microcomputer temperature controller, which has the characteristics of high temperature control accuracy.
Features
1. Adopt good cold-rolled plate spray chassis and stainless steel liner, the structure is strong and reliable.
2. The thermal insulation layer is foamed with a foaming agent, and the thermal insulation effect is good.
3. Adopted with microcomputer temperature controller for control, high temperature control accuracy.
4. Equipped with a circulating pump, the temperature in the working room can be uniform.
5. Provide a variety of Operating Modes (such as "dual control", "direct cooling") to adapt to different temperature control accuracy requirements.
Principle
The equipment sets and controls the target temperature through a microcomputer temperature controller. The heating system heats according to the set value, while the Compressor refrigeration system can cool down. The user can turn on the circulation pump to circulate the liquid in the Tank to ensure uniform temperature. High Accuracy temperature control can be achieved through parameter adjustment (such as P value, CT value) or self-tuning function of the temperature controller.
Applications
Biological, chemical, physical, plant, chemical and other scientific research
Standards
The data did not mention specific compliance criteria.
Steps
1. Read the instructions carefully before use and become familiar with the instrument.
2. Add refrigeration solution (such as distillation water, alcohol) to the overflow position.
3. Turn on the power switch to "ON" and set the desired temperature on the thermostat.
4. The circulating pump switch can be turned on to circulate the liquid internally, resulting in a more uniform temperature.
5. Usually turn the cooling switch in the "dual control" position, and set the CL, P, and CT parameters of the temperature controller according to the difference between the Ambient Temperature and the experimental temperature.
6. If the temperature control accuracy is very high （≤ +/- 0.2 ° C), the refrigeration switch can be turned to the "direct cooling" position and the self-tuning function of the temperature controller can be started.
Notice
• It is better to choose distillation water, alcohol, etc. for refrigeration medium, and it is strictly forbidden to use corrosion solutions such as sodium chloride.
• When using the pump externally, the horizontal position of the external water bath should be higher than that of this equipment, and the water inlet pipe should be placed at the bottom, and the water outlet pipe should be on the top. Before use, add a certain liquid to the external water bath, then connect the pipeline and turn on the water pump to prevent the liquid in the tank of this equipment from being evacuated and causing damage to the heating pipe.
• Pay attention to cleanliness when using to prevent liquid from splashing into the controller, so as not to cause control circuit failure, damage or leakage.
