Overview
DADI CHD-2030 Low Temperature Circulating Bath is a precision thermostatic device controlled by a microcomputer temperature controller. The chassis is made of cold-rolled plate spraying, the liner is made of stainless steel, and the foam insulation layer is used. It has the characteristics of good thermal insulation effect, strong and reliable. It 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 adopts a good cold-rolled plate spraying process, which is sturdy and durable.
3.The liner is made of good stainless steel, easy to clean and maintain.
4. The thermal insulation layer is foamed with a foaming agent, and the thermal insulation effect is good.
5. Equipped with a circulating pump, the temperature in the working room can be uniform.
Principle
The device sets and controls the target temperature through a microcomputer temperature controller. The heating system works according to the difference between the set temperature and the Ambient Temperature, and the refrigeration system (Compressor) can be started as needed to precisely control the temperature of the medium in the Tank. The user can turn on the circulation pump to circulate the liquid in the Tank to ensure Temperature uniformity.
Applications
Biological, chemical, physical, plant, chemical and other scientific research
Steps
1. Read the instructions carefully before use.
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. The circulating pump switch can be turned on to circulate the liquid to ensure uniform temperature.
5. According to the temperature control accuracy requirements, select the "dual control" or "direct cooling" mode of the refrigeration switch, and refer to the manual to set the relevant parameters of the temperature controller (such as CL, P value, CT).
6. If the accuracy requirements are high （≤ +/- 0.2 ° C), you can select the "direct cooling" mode and start the self-tuning function of the temperature controller.
Notice
• Refrigeration medium should be distillation water, alcohol, etc. It is strictly forbidden to use sodium chloride and other corrosion solutions.
• 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 at the bottom and the water outlet pipe should be at the upper part. 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 equipment from being evacuated and causing the heating pipe to dry burn and damage.
When using, pay attention to keep it clean and tidy to prevent liquid from splashing into the controller, so as not to cause line failure, damage or leakage.
