Overview
DH40-30 Low Temperature Circulating Bath is one of the BINGLIN brand DH series products. It provides a precise thermostatic, hot and cold controlled standard environment for various laboratory testing and analysis research institutions. It can be used as a cold source and heat source for direct or indirect heating and cooling. This model has 0.01 ℃ high resolution ， +/- 0.05 ℃ Temperature Fluctuation, Temperature range -40~ 100 ℃, Tank volume is 420 * 330 * 230mm ³.
Features
Automatic thermostatic Control system: using self-developed temperature control technology with PT100 and imported electronic components, the software system can correct the display error (resolution 0.001 ℃), PID temperature control can automatically or manually adjust the parameters, with digital locking function to prevent misoperation, accurate temperature control, fast and stable, after shutdown can still display the natural temperature changes in the tank.
2. Refrigeration system: using an effective fully enclosed Compressor for refrigeration, with fast cooling speed and multiple protections such as overheating and overcurrent.
3. Circulation system: with professional domestic circulation to make the temperature uniform and stable; can be changed to external circulation system, external circulation pump can output thermostatic liquid to establish the second thermostatic field outside the machine or as a cold source to chill down the experimental container outside the machine.
4. Alarm system: with over-temperature protection, over-temperature alarm function, can set over-temperature alarm temperature, over-temperature can automatically cut off the load.
Optional RS232 or RS485 interface.
Principle
The Low Temperature Circulating Bath precisely controls the operation of the heating and cooling system through an automatic thermostatic Control system combined with the PT100 temperature sensor and PID algorithm to achieve rapid stability and accurate maintenance of temperature in the Tank. The domestic circulation system ensures uniform temperature in the tank, and the external circulation system can pump out the thermostatic medium for temperature control or chill down of external equipment.
Applications
Laboratory testing, analysis and research institutions
Steps
1. Connect the power supply.
2. Set parameters such as target temperature and over-temperature alarm temperature as required.
3. Start the device, and the system will automatically control the temperature to reach the set value and maintain stability.
4. The domestic circulation or external circulation mode can be selected according to the experimental needs.
5. After use, press the "Power" button to turn off the function of the instrument, and the instrument will still display the temperature change in the slot.
Notice
• Software digital locking function can prevent unrelated personnel from misusing and ensure that the experimental data is correct.
• The equipment has over-temperature protection and alarm functions, and the load will be automatically cut off when overheating. Please pay attention to the alarm prompt when using it.
• The external circulation function can be used to establish a second thermostatic field outside the machine or chill down the external container, please connect and use it correctly according to your needs.
• After shutting down, the device still displays the temperature in the tank, please pay attention to distinguish the working status of the device.
• Optional Communication interface (RS232/RS485), please confirm the configuration if you need to use it.
