Overview
PINGXUAN DC1010-II High and Low Temperature Thermostatic bath is a device that provides an accurate and stable temperature environment for scientific research and production. It can provide a cold and hot controlled, uniform and constant temperature field source for experimental samples or product testing, and can also be used as a direct or auxiliary heating/cooling heat or cold source.
Features
1. Adopt self-developed special software temperature control technology, with High Accuracy PT100 and imported electronic components, accurate temperature control.
2. The software system supports temperature correction, with resolution up to 0.01 ° C to ensure accurate display temperature.
3. With over-temperature protection and alarm function, the alarm temperature can be set, and the load can be automatically cut off when the temperature is exceeded, which is safe and reliable.
4. Intelligent PID control system can automatically adjust parameters, Stability, special users can also adjust manually.
5. The software digital locking function can prevent misoperation and ensure that the experimental data is correct.
6. Adopt high-efficiency fully enclosed Compressor for refrigeration, with fast cooling speed and multiple protections.
7. With professional domestic circulation and external circulation system, domestic circulation ensures uniform temperature in the tank, and external circulation can establish a second thermostatic field outside the machine or as a cold source.
8. The power button can turn off the function of the instrument, but it can still display the natural temperature change process in the tank.
Principle
The equipment monitors the temperature in the working tank in real time through the High Accuracy temperature sensor (PT100), and transmits the signal to the self-developed intelligent control system. The system precisely adjusts the power output of the heating or cooling system (fully enclosed Compressor) through the PID algorithm, and uses the domestic circulation pump to make the medium in the tank flow continuously to ensure that the temperature is highly uniform and stable. The external circulation pump can output the thermostatic medium for establishing an external thermostatic environment or chilling down an external experimental vessel.
Applications
Research departments of petroleum, chemical industry, electronic instrumentation, physics, chemistry, biological engineering, life science, light industry food property testing, chemical analysis, etc., colleges and universities, enterprise Quality control and production departments
Steps
1. Preparation: Make sure that the equipment is placed in a smooth and ventilated place and connected to the power supply. According to the experimental requirements, add an appropriate amount of heat transfer medium to the working tank.
2. Boot and setting: Turn on the power switch and set the required target temperature, over-temperature alarm temperature and other parameters through the control panel.
3. Operation: Start the equipment, the refrigeration/heating system and the circulating pump to work, so that the temperature in the tank can quickly reach and stabilize at the set value.
4. Use: Put the experimental sample into the working tank or connect the external circulation pipeline for thermostatic experiment or test.
5. Monitoring and adjustment: During the experiment, the real-time temperature can be monitored through the display screen, and temperature correction or parameter adjustment can be carried out through software if necessary.
6. Shutdown: After the experiment, press the "Power" button to turn off the instrument function (the temperature in the tank is still displayed at this time), and then disconnect the power supply. Clean the working tank.
Notice
• Please read the instructions carefully before use to ensure that it operates under the specified environment conditions.
The liquid level of the heat transfer medium added should be appropriate to avoid overfilling or underfilling, and to ensure that the properties of the medium meet the requirements of the equipment.
When setting the over-temperature alarm temperature, it should be set within a safe range to play an effective protective role.
• During the operation of the equipment, do not block the ventilating port to ensure good heat dissipation.
• When making temperature corrections or parameter adjustments, it should be operated by trained personnel to avoid misoperation by unrelated personnel.
• The external circulation pipeline connection should be firm to prevent leakage.
• When the equipment is not used for a long time, the medium in the working tank should be emptied to keep it clean and drying.
• In case of fault alarm, the cause should be identified and eliminated before use. Do not force operation.
