Overview
DADI CHD-4015 Low Temperature Circulating Bath is a precision thermostatic device controlled by a microcomputer temperature controller. The chassis is made of cold-rolled plate spray, the liner is made of stainless steel, and the foaming agent is used for thermal insulation. It has the characteristics of good thermal insulation effect, strong and reliable, and is suitable for precision thermostatic experiments in biological, chemical, physical, plant, chemical and other scientific research fields.
Features
1. Using microcomputer temperature controller control, high temperature control accuracy.
2. The chassis is carefully made of good cold-rolled plate spraying, and the liner is made of good stainless steel, which is strong and reliable.
3. The thermal insulation layer is foamed with a foaming agent, and the thermal insulation effect is good.
4. Equipped with a circulating pump, the temperature in the working room can be uniform.
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 circulating pump switch to circulate the liquid in the tank to ensure uniform temperature in the working room. High Accuracy temperature control can be achieved through the parameter setting of the intelligent temperature controller (such as P value, CT value) or the activation of the self-setting function.
Applications
Biological, chemical, physical, plant, chemical and other scientific research
Steps
1. Read the instructions carefully before use.
2. Add the refrigeration solution to the overflow port.
3. Turn on the power switch, set the required temperature on the thermostat, and turn on the circulating pump switch to circulate the liquid.
4. During normal use, the refrigeration switch is in the "dual control" position, and the CL, P, and CT parameters of the intelligent temperature controller are set according to the difference between the Ambient Temperature and the experimental temperature. If the temperature control accuracy requirements are high （≤ +/- 0.2 ° C), the refrigeration switch can be turned to the "direct cooling" position, and the self-setting function of the temperature controller can be started. After the RUN light is normally on, it will enter the normal thermostatic state.
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 level of the external water bath should be higher than that of the super constant temperature water bath, and the water inlet pipe should be placed at the bottom and the water outlet pipe should be above. Before use, add a certain amount of water to the external water bath, then connect the pipeline and turn on the water pump to prevent the heating pipe from being damaged when exposed to the water.
• Pay attention to cleanliness when using to prevent water bath liquid from splashing into the controller, so as not to cause control circuit failure, damage or leakage.
