Overview
DADI CHD-3015 Low Temperature Circulating Bath is a precision thermostatic equipment suitable for biological, chemical, physical, plant, chemical and other scientific research fields. The chassis of this product is made of cold-rolled plate spraying, the liner is made of stainless steel, and the foam insulation layer is used. The thermal insulation effect is good and the structure is reliable. The whole machine is controlled by a microcomputer temperature controller, which has the advantages 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. Using foaming agent for heat preservation, the heat preservation effect is good.
3. Equipped with microcomputer temperature controller, high temperature control accuracy.
4. Provide a circulating pump to ensure even temperature in the working room.
5. With Compressor refrigeration function, Temperature range is wide.
Principle
The device sets and controls the target temperature through a microcomputer thermostat. According to the difference between the set value and the actual temperature, the system is heated by a heating power 800W or cooled by a Compressor refrigeration system to achieve precise temperature adjustment. The built-in circulating pump (Flow rate 6L/min) allows the liquid in the Tank to circulate and flow, ensuring Temperature uniformity.
Applications
Biological, chemical, physical, plant, chemical and other scientific research
Steps
1. Read the instructions carefully before use and become familiar with the instrument.
2. Add the refrigeration solution (e.g. distillation water, alcohol) to the overflow port.
3. Turn on the power switch and set the required temperature on the thermostat.
4. Turn on the circulating pump switch to circulate the liquid internally and maintain a uniform temperature.
5. During normal use, the refrigeration switch is in the "dual control" position, and according to the difference between the Ambient Temperature and the experimental temperature, parameters such as CL, P, CT are set on the temperature controller.
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.
• The pump can be used externally, but the level of the external water bath should be higher than that of this equipment, and the water inlet pipe is at the bottom and the water outlet pipe is above. When using externally, you need to add a certain liquid to the external water bath first, and then turn on the water pump to prevent the liquid in 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, causing malfunctions or leakage.
